Is 21 a factor of 675?

Here we will show you two different methods you can use to determine if 21 is a factor of 675.

The first method entails simply listing all factors of 675 and then seeing if 21 is one of them. The factors of 675 are 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, and 675. Looking at the list, you see that 21 is not on the list, and the answer to "Is 21 a factor of 675?" is therefore no.

For the second and perhaps easier method, we divide 675 by 21 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 21 is a factor of 675. If the quotient is a fractional number, then 21 is not a factor of 675.

675 divided by 21 is 32.14285714 which is a fractional number. Thus, once again, the answer to "Is 21 a factor of 675?" is no.
