Is 4 a factor of 30?

Here we will show you two different methods you can use to determine if 4 is a factor of 30.

The first method entails simply listing all factors of 30 and then seeing if 4 is one of them. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. Looking at the list, you see that 4 is not on the list, and the answer to "Is 4 a factor of 30?" is therefore no.

For the second and perhaps easier method, we divide 30 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 30. If the quotient is a fractional number, then 4 is not a factor of 30.

30 divided by 4 is 7.5 which is a fractional number. Thus, once again, the answer to "Is 4 a factor of 30?" is no.
