What is the 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.

Problem 1

Is 8,000 divisible by 400?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Yes, 8,000 is divisible by 400.

Explanation

To check if 8,000 is divisible by 400, we examine the last three digits of the number. Since the last three digits are "000," and 000 is divisible by 400, 8,000 is divisible by 400.

Problem 2

Check the divisibility rule of 400 for 2,400.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Yes, 2,400 is divisible by 400.
 

Explanation

For checking if 2,400 is divisible by 400, we look at the last three digits of the number, which are "400." Since 400 is divisible by 400 (400 × 1 = 400), 2,400 is divisible by 400.

Problem 3

Is 5,720 divisible by 400?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

No, 5,720 is not divisible by 400.
 

Explanation

To determine if 5,720 is divisible by 400, we check the last three digits, which are "720." Since 720 is not evenly divisible by 400 (720 ÷ 400 = 1.8), 5,720 is not divisible by 400.

Problem 4

Can 10,600 be divisible by 400 following the divisibility rule?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Yes, 10,600 is divisible by 400.
 

Explanation

To check if 10,600 is divisible by 400, we examine the last three digits: "600." Since 600 is divisible by 400 (400 × 1.5 = 600), 10,600 is divisible by 400.

Problem 5

Check the divisibility rule of 400 for 9,200.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

 Yes, 9,200 is divisible by 400.
 

Explanation

To check if 9,200 is divisible by 400, we look at the last three digits, which are "200." Since 200 is not divisible by 400, but 9200 is divisible by 400 (400 × 23 = 9200), 9,200 is divisible by 400.
