Is 18 a factor of 198?

Here we will show you two different methods you can use to determine if 18 is a factor of 198.

The first method entails simply listing all factors of 198 and then seeing if 18 is one of them. The factors of 198 are 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, and 198. Looking at the list, you see that 18 is on the list, and the answer to "Is 18 a factor of 198?" is therefore yes.

For the second and perhaps easier method, we divide 198 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 198. If the quotient is a fractional number, then 18 is not a factor of 198.

198 divided by 18 is 11 which is a whole number. Thus, once again, the answer to "Is 18 a factor of 198?" is yes.
