Is 49 a factor of 648?

Here we will show you two different methods you can use to determine if 49 is a factor of 648.

The first method entails simply listing all factors of 648 and then seeing if 49 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 49 is not on the list, and the answer to "Is 49 a factor of 648?" is therefore no.

For the second and perhaps easier method, we divide 648 by 49 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 49 is a factor of 648. If the quotient is a fractional number, then 49 is not a factor of 648.

648 divided by 49 is 13.2244898 which is a fractional number. Thus, once again, the answer to "Is 49 a factor of 648?" is no.
