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.

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.

• Divisibility rule: The set of rules used to determine whether a number is divisible by another number.
   
• Multiples: The results obtained after multiplying a number by an integer. For example, multiples of 131 are 131, 262, 393, etc.
   
• Estimation: A method of finding an approximate value that is close to the actual value, often used for quick calculations.
   
• Verification: The process of confirming the accuracy of a result, such as using division to check divisibility.
   
• Integers: Numbers that include all whole numbers, negative numbers, and zero.
