Divisibility Rule of 432

The divisibility rule for 432 is a method by which we can find out if a number is divisible by 432 or not without using the division method. Check whether 5184 is divisible by 432 with the divisibility rule.

Step 1: Check divisibility by 16: The last four digits of the number should be divisible by 16. For 5184, the last four digits are 5184, which is divisible by 16 (5184 ÷ 16 = 324).

Step 2: Check divisibility by 27: Sum the digits of the number and check if the result is divisible by 27. For 5184, the sum of the digits is 5 + 1 + 8 + 4 = 18. Since 18 is not divisible by 27, 5184 is not divisible by 432

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 432.

Know the multiples of 432:

Memorize the multiples of 432 (432, 864, 1296, 1728, etc.) to quickly check the divisibility. If the number is a multiple of 432, then it is divisible by 432.

Break down large numbers:

For large numbers, first, break them down by checking divisibility by smaller factors (16 and 27) of 432. If a number is divisible by both 16 and 27, it is divisible by 432.

Use the division method to verify:

Students can use the division method as a way to verify and crosscheck their results. This will help them verify and also learn.
