854 in binary is written as 1101010110 because the binary system uses only two digits, 0 and 1, to represent numbers. This number system is widely used in computer systems. In this topic, we are going to learn about the binary representation of 854.
The process of converting 854 from decimal to binary involves dividing the number 854 by 2. Here, it is divided by 2 because the binary number system uses only 2 digits (0 and 1). The quotient becomes the dividend in the next step, and the process continues until the quotient becomes 0.
This is a commonly used method to convert 854 to binary. In the last step, the remainder is noted down from bottom to top, and that becomes the converted value.
For example, the remainders noted down after dividing 854 by 2 until getting 0 as the quotient is 1101010110. Remember, the remainders here have been written upside down.
In the table shown below, the first column shows the binary digits (1 and 0) as 854.
The second column represents the place values of each digit, and the third column is the value calculation, where the binary digits are multiplied by their corresponding place values.
The results of the third column can be added to cross-check if 1101010110 in binary is indeed 854 in the decimal number system.
854 can be converted easily from decimal to binary. The methods mentioned below will help us convert the number. Let’s see how it is done.
Expansion Method: Let us see the step-by-step process of converting 854 using the expansion method.
Step 1 - Figure out the place values: In the binary system, each place value is a power of 2. Therefore, in the first step, we will ascertain the powers of 2. 20 = 1 21 = 2 22 = 4 23 = 8 24 = 16 25 = 32 26 = 64 27 = 128 28 = 256 29 = 512 Since 512 is less than 854, we start at 29 = 512.
Step 2 - Identify the largest power of 2: In the previous step, we started at 29 = 512. This is because in this step, we have to identify the largest power of 2, which is less than or equal to the given number, 854. Since 29 is the number we are looking for, write 1 in the 29 place. Now the value of 29, which is 512, is subtracted from 854. 854 - 512 = 342.
Step 3 - Identify the next largest power of 2: In this step, we need to find the largest power of 2 that fits into the result of the previous step, 342. So, the next largest power of 2 is 28 = 256. Now, we have to write 1 in the 2^8 place. And then subtract 256 from 342. 342 - 256 = 86.
Step 4 - Continue this process: Continue identifying the largest power of 2 and subtracting until the remainder is 0. 86 - 64 (26) = 22
22 - 16 (24) = 6
6 - 4 (22) = 2
2 - 2 (21) = 0
Step 5 - Identify the unused place values and write 0s: We used 29, 28, 26, 24, 22, and 21. Write 0s in 27, 25, 23, and 20 places. Now, by substituting the values, we get: 0 in the 20 place 1 in the 21 place 1 in the 22 place 0 in the 23 place 1 in the 24 place 0 in the 25 place 1 in the 26 place 0 in the 27 place 1 in the 28 place 1 in the 29 place
Step 6 - Write the values in reverse order: We now write the numbers upside down to represent 854 in binary. Therefore, 1101010110 is 854 in binary.
Grouping Method: In this method, we divide the number 854 by 2. Let us see the step-by-step conversion.
Step 1 - Divide the given number 854 by 2. 854 / 2 = 427. Here, 427 is the quotient and 0 is the remainder.
Step 2 - Divide the previous quotient (427) by 2. 427 / 2 = 213. Here, the quotient is 213 and the remainder is 1.
Step 3 - Repeat the previous step. 213 / 2 = 106. Now, the quotient is 106 and 1 is the remainder.
Step 4 - Continue until the quotient is 0: 106 / 2 = 53 (remainder 0) 53 / 2 = 26 (remainder 1) 26 / 2 = 13 (remainder 0) 13 / 2 = 6 (remainder 1) 6 / 2 = 3 (remainder 0) 3 / 2 = 1 (remainder 1) 1 / 2 = 0 (remainder 1)
Step 5 - Write down the remainders from bottom to top. Therefore, 854 (decimal) = 1101010110 (binary).
There are certain rules to follow when converting any number to binary. Some of them are mentioned below:
This is one of the most commonly used rules to convert any number to binary. The place value method is the same as the expansion method, where we need to find the largest power of 2. Let’s see a brief step-by-step explanation to understand the first rule. Find the largest power of 2 less than or equal to 854. Since the answer is 29, write 1 next to this power of 2. Subtract the value (512) from 854. So, 854 - 512 = 342. Find the largest power of 2 less than or equal to 342. The answer is 28. So, write 1 next to this power. Repeat the process until the remainder is 0. Write 0 next to unused powers. Final conversion will be 1101010110.
The division by 2 method is the same as the grouping method. A brief step-by-step explanation is given below for better understanding. First, 854 is divided by 2 to get 427 as the quotient and 0 as the remainder. Now, 427 is divided by 2. Here, we will get 213 as the quotient and 1 as the remainder. Continue the process until the quotient becomes 0. Now, we write the remainders upside down to get the binary equivalent of 854, 1101010110.
This rule also involves breaking the number into powers of 2. Identify the powers of 2 and write them down in decreasing order, i.e., 29, 28, 27, and so on. Find the largest power that fits into 854. Repeat the process and allocate 1s and 0s to the suitable powers of 2. Combine the digits (0 and 1) to get the binary result.
The limitation of the binary system is that only 0s and 1s can be used to represent numbers. The system doesn’t use any other digits other than 0 and 1. This is a base 2 number system, where the binary places represent powers of 2. So, every digit is either a 0 or a 1. To convert 854, we use 1s for 29, 28, 26, 24, 22, and 21.
Learning a few tips and tricks is a great way to solve any mathematical problems easily. Let us take a look at some tips and tricks for binary numbers up to 854.
Memorize to speed up conversions: We can memorize the binary forms for smaller numbers for quick conversions.
Recognize the patterns: There is a peculiar pattern when converting numbers from decimal to binary.
Even and odd rule: Whenever a number is even, its binary form will end in 0. For example, 854 is even, and its binary form is 1101010110. Here, the binary of 854 ends in 0. If the number is odd, then its binary equivalent will end in 1.
Cross-verify the answers: Once the conversion is done, we can cross-verify the answers by converting the number back to the decimal form. This will eliminate any unforeseen errors in conversion.
Practice by using tables: Writing the decimal numbers and their binary equivalents on a table will help us remember the conversions.
Here, let us take a look at some of the most commonly made mistakes while converting numbers to binary.
Convert 854 from decimal to binary using the place value method.
1101010110
29 is the largest power of 2, which is less than or equal to 854.
So place 1 next to 29.
Subtracting 512 from 854, we get 342.
The next largest power would be 2^8. So place another 1 next to 28.
Now, continue subtracting and placing 1s until the remainder is 0.
Place 0s in unused powers.
By using this method, we can find the binary form of 854.
Convert 854 from decimal to binary using the division by 2 method.
1101010110
Divide 854 by 2.
In the next step, the quotient becomes the new dividend.
Continue the process until the quotient becomes 0.
Now, write the remainders upside down to get the final result.
Convert 854 to binary using the representation method.
1101010110
Break the number 854 into powers of 2 and find the largest powers of 2.
We get 29.
So 1 is placed next to 29.
Next, 854 - 512 = 342.
Now, the largest power of 2 is 28.
Once again, 1 is placed next to 28.
Continue until the remainder is 0.
After getting 0, fill in with zeros for unused powers of 2.
By following this method, we get the binary value of 854 as 1101010110.
How is 854 written in decimal, octal, and binary form?
Decimal form - 854 Octal - 1516 Binary - 1101010110
The decimal system is also called the base 10 system.
In this system, 854 is written as 854 only.
We have already seen how 854 is written as 1101010110 in binary.
So, let us focus on the octal system, which is base 8.
To convert 854 to octal, we need to divide 854 by 8.
So 854 / 8 = 106 with a remainder of 6.
In the next step, divide 106 by 8.
So 106 / 8 = 13 with a remainder of 2.
Finally, divide 13 by 8 to get 1 with a remainder of 5.
The division process stops here because the quotient is now 0.
Here, 6, 2, and 5 are the remainders, and they have to be written in reverse order.
So, 1516 is the octal equivalent of 854.
Express 854 - 1 in binary.
1101010101
854 - 1 = 853 So, we need to write 853 in binary.
Start by dividing 853 by 2.
We get 426 as the quotient and 1 as the remainder.
Next, divide 426 by 2.
Now we get 213 as the quotient and 0 as the remainder.
Continue dividing until the quotient is 0.
Write the remainders from bottom to top to get 1101010101 (binary of 853).
