413 in binary is written as 110011101 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 413.
The process of converting 413 from decimal to binary involves dividing the number 413 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 413 to binary. In the last step, the remainder is noted down bottom side up, and that becomes the converted value. For example, the remainders noted down after dividing 413 by 2 until getting 0 as the quotient is 110011101. 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 110011101. 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 110011101 in binary is indeed 413 in the decimal number system.
413 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 413 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 greater than 413, we stop at 28 = 256.
Step 2 - Identify the largest power of 2: In the previous step, we stopped at 28 = 256. This is because, in this step, we have to identify the largest power of 2 that is less than or equal to the given number, 413. Since 28 is the number we are looking for, write 1 in the 28 place. Now the value of 28, which is 256, is subtracted from 413. 413 - 256 = 157.
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, 157. So, the next largest power of 2 is 27, which is less than or equal to 157. Now, we have to write 1 in the 27 place. And then subtract 128 from 157. 157 - 128 = 29.
Step 4 - Continue the process: Now, we find the next largest power of 2 for 29, which is 24. Write 1 in the 24 place. 29 - 16 = 13. The next power of 2 is 23. Write 1 in the 23 place. 13 - 8 = 5. The next power of 2 is 22. Write 1 in the 22 place. 5 - 4 = 1. The next power of 2 is 20. Write 1 in the 20 place. 1 - 1 = 0. We need to stop the process here since the remainder is 0.
Step 5 - Identify the unused place values: In the steps above, we wrote 1 in the 28, 27, 24, 23, 22, and 20 places. Now, we can just write 0s in the remaining places, which are 26, 25, and 21. By substituting the values, we get: 0 in the 21 place 1 in the 20 place 1 in the 22 place 1 in the 23 place 1 in the 24 place 0 in the 25 place 0 in the 26 place 1 in the 27 place 1 in the 28 place
Step 6 - Write the values in reverse order: We now write the numbers upside down to represent 413 in binary. Therefore, 110011101 is 413 in binary.
Grouping Method: In this method, we divide the number 413 by 2. Let us see the step-by-step conversion.
Step 1 - Divide the given number 413 by 2. 413 / 2 = 206. Here, 206 is the quotient and 1 is the remainder.
Step 2 - Divide the previous quotient (206) by 2. 206 / 2 = 103. Here, the quotient is 103 and the remainder is 0.
Step 3 - Repeat the previous step. 103 / 2 = 51. Now, the quotient is 51, and 1 is the remainder.
Step 4 - Repeat the previous step. 51 / 2 = 25. Here, the quotient is 25, and 1 is the remainder.
Step 5 - Continue the division process. 25 / 2 = 12. The quotient is 12, and the remainder is 1. 12 / 2 = 6. The quotient is 6, and the remainder is 0. 6 / 2 = 3. The quotient is 3, and the remainder is 0. 3 / 2 = 1. The quotient is 1, and the remainder is 1. 1 / 2 = 0. Here, the remainder is 1. We stop the division here because the quotient is 0.
Step 6 - Write down the remainders from bottom to top. Therefore, 413 (decimal) = 110011101 (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 413. Since the answer is 28, write 1 next to this power of 2. Subtract the value (256) from 413. So, 413 - 256 = 157. Find the largest power of 2 less than or equal to 157. The answer is 27. So, write 1 next to this power. Now, 157 - 128 = 29. Find the largest power of 2 less than or equal to 29. The answer is 24. So, write 1 next to this power. 29 - 16 = 13. Continue this process for the remaining values. The final conversion will be 110011101.
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, 413 is divided by 2 to get 206 as the quotient and 1 as the remainder. Now, 206 is divided by 2. Here, we will get 103 as the quotient and 0 as the remainder. Continue dividing the quotient by 2, writing the remainder for each division. Stop the division once the quotient becomes 0. Now, we write the remainders upside down to get the binary equivalent of 413, which is 110011101.
This rule also involves breaking of the number into powers of 2. Identify the powers of 2 and write them down in decreasing order i.e., 28, 27, 26, and so on. Find the largest power that fits into 413. 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 413, we use 0s for 26, 25, and 21, and 1s for 28, 27, 24, 23, 22, and 20.
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 413.
Here, let us take a look at some of the most commonly made mistakes while converting numbers to binary.
Convert 413 from decimal to binary using the place value method.
110011101
28 is the largest power of 2, which is less than or equal to 413.
So place 1 next to 28.
Subtracting 256 from 413, we get 157.
The next largest power is 27.
Place another 1 next to 27.
Now, subtracting 128 from 157, we get 29.
Continue this process until you reach 0.
By using this method, we can find the binary form of 413.
Convert 413 from decimal to binary using the division by 2 method.
110011101
Divide 413 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 413 to binary using the representation method.
110011101
Break the number 413 into powers of 2 and find the largest powers of 2.
We get 28. So 1 is placed next to 28.
Next, 413 - 256 = 157.
Now, the largest power of 2 is 27.
Once again, 1 is placed next to 27.
Continue this process, filling in 0s for unused powers of 2.
By following this method, we get the binary value of 413 as 110011101.
How is 413 written in decimal, octal, and binary form?
Decimal form - 413 Octal - 635 Binary - 110011101
The decimal system is also called the base 10 system. In this system, 413 is written as 413.
We have already seen how 413 is written as 110011101 in binary.
So, let us focus on the octal system, which is base 8.
To convert 413 to octal, we need to divide 413 by 8.
So 413 / 8 = 51 with 5 as the remainder. In the next step, divide the quotient from the previous step (51) by 8. So 51 / 8 = 6 with 3 as the remainder.
The division process stops here because the quotient is now 0.
Here, 5, 3, and 6 are the remainders, and they have to be written in reverse order.
So, 635 is the octal equivalent of 413.
Express 413 - 123 in binary.
100010000
413 - 123 = 290 So, we need to write 290 in binary.
Start by dividing 290 by 2.
We get 145 as the quotient and 0 as the remainder.
Next, divide 145 by 2. Now we get 72 as the quotient and 1 as the remainder.
Continue dividing the quotient by 2 until you reach 0.
Now write the remainders from bottom to top to get 100010000 (binary of 290).
