# How do you check if a number is evenly divisible by another number?

A number is divisible by another number if it can be divided equally by that number; that is, if it yields a whole number when divided by that number. For example, 6 is divisible by 3 (we say “3 divides 6”) because 6/3 = 2, and 2 is a whole number.
