Is 21 a factor of 372?

Here we will show you two different methods you can use to determine if 21 is a factor of 372.

The first method entails simply listing all factors of 372 and then seeing if 21 is one of them. The factors of 372 are 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, and 372. Looking at the list, you see that 21 is not on the list, and the answer to "Is 21 a factor of 372?" is therefore no.

For the second and perhaps easier method, we divide 372 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 372. If the quotient is a fractional number, then 21 is not a factor of 372.

372 divided by 21 is 17.71428571 which is a fractional number. Thus, once again, the answer to "Is 21 a factor of 372?" is no.
