Divisibility Rule of 4

The Rule for 4: If the last two digits of a whole number are divisible by 4, then the entire number is divisible by 4.

Illustration: Check whether 456,791,824 is divisible by 4 or not? Solution: For this rule, we will look at the last two digits: 456,791,824. Does 4 divide evenly into 24? Yes. That means that 4 will also divide evenly into 456,791,824 and there will be no remainder. Illustration: Check whether 726,810 is divisible by 4 or not? Solution: We will take a look at the last two digits: 723,810. Does 4 divide evenly into 10? No. That means that 4 will not divide evenly into 7223,810 and there will be a remainder.

Illustration: Check which of the following numbers are divisible by 4?

                   1256, 5614, 2532

Solution: As the last two digits in 1256 and 2532 are divisible by 4, Hence these two numbers are divisible by 4. But the last two digits in 5614 are not divisible by 4, Hence 5614 is not divisible by 4.

Illustration: Check which of the following numbers are divisible by 4?

                      10004, 2000, - 1436
