Divisibility Rule of 246

The divisibility rule for 246 is a method by which we can find out if a number is divisible by 246 without using the division method. Check whether 1476 is divisible by 246 using the divisibility rule.

Step 1: Check if the number is divisible by 2, 3, and 41, since 246 = 2 × 3 × 41. 

Step 2: For divisibility by 2, the last digit should be even. Here, in 1476, the last digit is 6, which is even.

Step 3: For divisibility by 3, the sum of all digits should be divisible by 3. Here, 1+4+7+6 = 18, and 18 is divisible by 3.

Step 4: For divisibility by 41, perform the division to verify or use a calculator. Here, 1476 ÷ 41 = 36, which is an integer.

Since 1476 is divisible by 2, 3, and 41, it is also divisible by 246.
 

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 246.

Know the prime factors:

Memorize the prime factors of 246 (2, 3, 41) to quickly check divisibility.

Use divisibility tests for smaller factors:

If a number is divisible by all the prime factors of 246, it is divisible by 246.

Repeat the process for large numbers:

For large numbers, check divisibility by 2, 3, and 41 separately and ensure all conditions are met.

Use a calculator for verification:

Students can use a calculator to verify and cross-check their results.
