How can we tell if a number is divisible by 4?

Question

Question 6 options:

A)

The sum of the digits is 4

B)

The last two digits of the number are divisible by 4

C)

The sum of the digits is divisible by 4

D)

The last digit is divisible by 4

Answer 1

To determine if a number is divisible by 4, you can check B) The last two digits of the number are divisible by 4.

This means that if you take the last two digits of any number and see if that two-digit number can be divided by 4 without a remainder, then the whole number is divisible by 4.

For example, if the number is 123456, you would take the last two digits, which are 56, and check if 56 is divisible by 4. Since 56 ÷ 4 = 14, it indicates that 123456 is divisible by 4 as well.

The other options provided do not correctly determine divisibility by 4.
