Divisibility Rule of 131
The divisibility rule is a way to determine whether a number is divisible by another number without using the division method. In real life, we can use divisibility rules for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 131.
What is the Divisibility Rule of 131?
The divisibility rule for 131 is a method by which we can determine if a number is divisible by 131 without using the division method. Let's check whether 2620 is divisible by 131 using the divisibility rule.
Step 1: Break the number into smaller parts or known multiples of 131. Here, 2620 can be broken into 2600 and 20.
Step 2: Check if each part is divisible by 131. Since 131 × 20 = 2620, the number is divisible by 131.

Tips and Tricks for Divisibility Rule of 131
Learning divisibility rules helps students master division. Let’s learn a few tips and tricks for the divisibility rule of 131.
- Know the multiples of 131: Memorize the multiples of 131 (131, 262, 393, 524, 655…etc.) to quickly check divisibility. If the sum of parts is a multiple of 131, the number is divisible by 131.
- Use estimation: For large numbers, estimate whether the number can be a multiple of 131 by comparing it to known multiples.
- Break down large numbers: If a number is too large, break it down into smaller components or sums that are easier to manage.
- Use the division method to verify: Students can use the division method to verify and crosscheck their results. This will help them verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 131
The divisibility rule of 131 helps us quickly check if a given number is divisible by 131, but common mistakes like calculation errors can lead to incorrect conclusions. Here are some common mistakes and how to avoid them.
Mistake 1
Not following the correct steps.
Students should follow the correct steps of breaking down the number into manageable parts and checking each part for divisibility by 131.
Mistake 2
Forgetting to verify each part.
Ensure that each broken-down part is checked for divisibility by 131.
Mistake 3
Not using estimation.
Use estimation to quickly determine if a number could be divisible by 131, especially when dealing with large numbers.
Mistake 4
Skipping verification.
Always verify with actual division to confirm the result.
Mistake 5
Confusing the steps.
Students often confuse the steps or forget them. Regular practice can help avoid this error.

Explanation
To check if 262 is divisible by 131:
1) Divide the number by 131, 262 ÷ 131 = 2.
2) The division results in an integer (2), so 262 is divisible by 131.
Problem 2
Check the divisibility rule of 131 for 393.
Yes, 393 is divisible by 131.
Explanation
For checking the divisibility rule of 131 for 393:
1) Divide the number by 131, 393 ÷ 131 = 3.
2) The division results in an integer (3), so 393 is divisible by 131.
Problem 3
Is 655 not divisible by 131?
Yes, 655 is divisible by 131.
Explanation
To check if 655 is divisible by 131:
1) Divide the number by 131, 655 ÷ 131 = 5.
2) The division results in an integer (5), so 655 is divisible by 131.
Problem 4
Can 780 be divisible by 131 following the divisibility rule?
No, 780 isn't divisible by 131.
Explanation
To check if 780 is divisible by 131:
1) Divide the number by 131, 780 ÷ 131 ≈ 5.954.
2) The division does not result in an integer, so 780 is not divisible by 131.
Problem 5
Check the divisibility rule of 131 for 1048.
No, 1048 is not divisible by 131.
Explanation
To check the divisibility rule of 131 for 1048:
1) Divide the number by 131, 1048 ÷ 131 ≈ 8.
2) The division does not result in an integer, so 1048 is not divisible by 131.
