Is 25 a factor of 687?

Here we will show you two different methods you can use to determine if 25 is a factor of 687.

The first method entails simply listing all factors of 687 and then seeing if 25 is one of them. The factors of 687 are 1, 3, 229, and 687. Looking at the list, you see that 25 is not on the list, and the answer to "Is 25 a factor of 687?" is therefore no.

For the second and perhaps easier method, we divide 687 by 25 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 25 is a factor of 687. If the quotient is a fractional number, then 25 is not a factor of 687.

687 divided by 25 is 27.48 which is a fractional number. Thus, once again, the answer to "Is 25 a factor of 687?" is no.
