Divisibility Rule of 481
The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 481.
What is the Divisibility Rule of 481?
The divisibility rule for 481 is a method by which we can determine if a number is divisible by 481 without using the division method. Let's check whether 1443 is divisible by 481 with the divisibility rule.
Step 1: Take the last digit of the number. Here, in 1443, 3 is the last digit.
Step 2: Multiply this last digit by 2 and subtract it from the remaining number formed by the other digits. So, 3×2=6 and 144-6=138.
Step 3: Repeat the process until you reach a number that is manageable. Since 138 is not a multiple of 481, we will continue the process (if necessary).
Step 4: If the result obtained is a multiple of 481, then the original number is divisible by 481. Otherwise, it is not. Since 138 is not a multiple of 481, 1443 is not divisible by 481.
Tips and Tricks for Divisibility Rule of 481
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 481.
- Know the multiples of 481: Memorize the multiples of 481 (481, 962, 1443, etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 481, then the number is divisible by 481.
- Use the negative numbers: If the result we get after the subtraction is negative, we will avoid the symbol and consider it as positive for checking the divisibility of a number.
- Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a small number that is manageable and check for divisibility.
- Use the division method to verify: Students can use the division method as a way to verify and cross-check their results. This will help them verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 481
The divisibility rule of 481 helps us quickly check if a given number is divisible by 481, but common mistakes like calculation errors lead to incorrect results. Here, we will understand some common mistakes to avoid.
Mistake 1
Not following the correct steps.
Students should follow the correct steps, including multiplying the last digit by 2 and subtracting the result from the remaining digits excluding the last digit.
Mistake 2
Including the last digit in subtraction.
Students should exclude the last digit while subtracting and include all the remaining digits.
Mistake 3
Not repeating the process when the result is large.
Students often stop the process after they have a large result. The process should be repeated until a manageable number is reached to check for divisibility.
Mistake 4
Not considering the negative values.
Students might ignore negative values, thinking divisibility rules don't apply to them. However, the divisibility rule applies to negative values as well. Consider negative values as positive when checking for divisibility.
Mistake 5
Confusing the steps.
Students often confuse or forget the steps. To avoid errors, students should practice regularly.
Divisibility Rule of 481 Examples
Problem 1
Is 1443 divisible by 481?
No, 1443 is not divisible by 481.
Explanation
To check divisibility by 481, we can use a similar approach to other divisibility rules, though a specific rule for 481 doesn't exist like smaller numbers. We divide 1443 by 481 directly using long division to see if it results in a whole number. 1443 ÷ 481 ≈ 3, remainder 0. Since there is no remainder, 1443 is not divisible by 481.
Problem 2
Check if 4810 is divisible by 481.
Yes, 4810 is divisible by 481.
Explanation
Using long division, we divide 4810 by 481. 4810 ÷ 481 = 10, remainder 0. Since there is no remainder, 4810 is divisible by 481.
Problem 3
Is 962 divisible by 481?
Yes, 962 is divisible by 481.
Explanation
To check if 962 is divisible by 481, divide 962 by 481. 962 ÷ 481 = 2, remainder 0. With no remainder, 962 is divisible by 481.
Problem 4
Can 2405 be divisible by 481?
No, 2405 is not divisible by 481.
Explanation
To determine if 2405 is divisible by 481, perform the division. 2405 ÷ 481 ≈ 5, remainder 0. As there is a remainder, 2405 is not divisible by 481.
Problem 5
Check if 5772 is divisible by 481.
No, 5772 is not divisible by 481.
Explanation
Perform the division of 5772 by 481. 5772 ÷ 481 ≈ 12, remainder 0. The presence of a remainder means 5772 is not divisible by 481.
