Divisibility Rule of 655

The divisibility rule for 655 is a method by which we can find out if a number is divisible by 655 or not without using the division method.

Check whether 327625 is divisible by 655 with the divisibility rule.

Step 1: Check if the last three digits of the number are divisible by 655. Here, in 327625, the last three digits are 625.

Step 2: Since 625 is less than 655, check if the entire number 327625 is divisible by 655.

Step 3: If the number 327625 is divisible by 655, the result should be an integer without a remainder.

Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 655.

• Know the multiples of 655:  Memorize the multiples of 655 (655, 1310, 1965, 2620, etc.) to quickly check the divisibility. If the last three digits form a number that is a multiple of 655, the original number is divisible by 655.
   
• Use estimation for large numbers: For large numbers, estimate if the last three digits are close to a multiple of 655. This can help in quickly identifying 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 to verify and also learn.

• Divisibility rule: The set of rules used to find out whether a number is divisible by another number or not.
   
• Multiples: The results we get after multiplying a number by an integer. For example, multiples of 655 are 655, 1310, 1965, etc.
   
• Integer: Numbers that include all whole numbers, negative numbers, and zero.
   
• Estimation: A method to find an approximate value, often used for quick calculations.
   
• Verification: Cross-checking results, often using an alternative method like actual division, to ensure accuracy.
