Is 42 a factor of 648?

Here we will show you two different methods you can use to determine if 42 is a factor of 648.

The first method entails simply listing all factors of 648 and then seeing if 42 is one of them. The factors of 648 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, and 648. Looking at the list, you see that 42 is not on the list, and the answer to "Is 42 a factor of 648?" is therefore no.

For the second and perhaps easier method, we divide 648 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 648. If the quotient is a fractional number, then 42 is not a factor of 648.

648 divided by 42 is 15.42857143 which is a fractional number. Thus, once again, the answer to "Is 42 a factor of 648?" is no.
