Is 18 a factor of 197?

Here we will show you two different methods you can use to determine if 18 is a factor of 197.

The first method entails simply listing all factors of 197 and then seeing if 18 is one of them. The factors of 197 are 1 and 197. Looking at the list, you see that 18 is not on the list, and the answer to "Is 18 a factor of 197?" is therefore no.

For the second and perhaps easier method, we divide 197 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 197. If the quotient is a fractional number, then 18 is not a factor of 197.

197 divided by 18 is 10.94444444 which is a fractional number. Thus, once again, the answer to "Is 18 a factor of 197?" is no.
