Is 18 a factor of 625?

Here we will show you two different methods you can use to determine if 18 is a factor of 625.

The first method entails simply listing all factors of 625 and then seeing if 18 is one of them. The factors of 625 are 1, 5, 25, 125, and 625. Looking at the list, you see that 18 is not on the list, and the answer to "Is 18 a factor of 625?" is therefore no.

For the second and perhaps easier method, we divide 625 by 18 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 18 is a factor of 625. If the quotient is a fractional number, then 18 is not a factor of 625.

625 divided by 18 is 34.72222222 which is a fractional number. Thus, once again, the answer to "Is 18 a factor of 625?" is no.
