Divisibility Rule of 331

The divisibility rule for 331 is a method by which we can find out if a number is divisible by 331 without using the division method. Let's check whether 662 is divisible by 331 using this rule.

Step 1: Identify if there is a simple rule or pattern. In this case, there is no straightforward rule like for smaller numbers, so we need to verify directly or use known multiples if available.

Step 2: Since 662 is a small number, we can check directly or compare with known multiples of 331. 

Step 3: Divide 662 by 331. If the result is an integer, then 662 is divisible by 331.

Understanding divisibility rules helps children master division. Let's learn some tips and tricks for the divisibility rule of 331.

• Know the multiples of 331: Memorize the multiples of 331 (331, 662, 993, etc.) to quickly check divisibility. If the number matches any of these multiples, it is divisible by 331.

• Large numbers: For large numbers, compare with known multiples of 331 or perform direct division for verification.

• Use the division method to verify: Students can use the division method as a way to verify and crosscheck their results, which aids in learning and verification.

• Divisibility: The ability of one number to be divided by another without leaving a remainder.

• Multiples: Results obtained by multiplying a number by an integer. For example, multiples of 331 are 331, 662, 993, etc.

• Integer: A whole number that can be positive, negative, or zero.

• Remainder: The amount left over after division when one number cannot be exactly divided by another.

• Verification: The process of confirming or proving the accuracy of a calculation or result, often through division in this context.
