Is 4 a factor of 18?

Here we will show you two different methods you can use to determine if 4 is a factor of 18.

The first method entails simply listing all factors of 18 and then seeing if 4 is one of them. The factors of 18 are 1, 2, 3, 6, 9, and 18. Looking at the list, you see that 4 is not on the list, and the answer to "Is 4 a factor of 18?" is therefore no.

For the second and perhaps easier method, we divide 18 by 4 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 4 is a factor of 18. If the quotient is a fractional number, then 4 is not a factor of 18.

18 divided by 4 is 4.5 which is a fractional number. Thus, once again, the answer to "Is 4 a factor of 18?" is no.
