Is 42 a factor of 378?

Here we will show you two different methods you can use to determine if 42 is a factor of 378.

The first method entails simply listing all factors of 378 and then seeing if 42 is one of them. The factors of 378 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, and 378. Looking at the list, you see that 42 is on the list, and the answer to "Is 42 a factor of 378?" is therefore yes.

For the second and perhaps easier method, we divide 378 by 42 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 42 is a factor of 378. If the quotient is a fractional number, then 42 is not a factor of 378.

378 divided by 42 is 9 which is a whole number. Thus, once again, the answer to "Is 42 a factor of 378?" is yes.
