Divisibility Rule of 400

The divisibility rule for 400 is a method by which we can find out if a number is divisible by 400 or not without using the division method. Check whether 2400 is divisible by 400 with the divisibility rule.

Step 1: Check the last three digits of the number. In 2400, the last three digits are 400.

Step 2: If the last three digits form a number that is exactly divisible by 400, then the whole number is divisible by 400. Since 400 is exactly divisible by 400, 2400 is divisible by 400.

Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 400.

Know the multiples of 400:

Memorize the multiples of 400 (400, 800, 1200, 1600, etc.) to quickly check divisibility. If the last three digits form a multiple of 400, then the number is divisible by 400.

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 their answers and also learn.
