Is 49 a factor of 640?

Here we will show you two different methods you can use to determine if 49 is a factor of 640.

The first method entails simply listing all factors of 640 and then seeing if 49 is one of them. The factors of 640 are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, and 640. Looking at the list, you see that 49 is not on the list, and the answer to "Is 49 a factor of 640?" is therefore no.

For the second and perhaps easier method, we divide 640 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 640. If the quotient is a fractional number, then 49 is not a factor of 640.

640 divided by 49 is 13.06122449 which is a fractional number. Thus, once again, the answer to "Is 49 a factor of 640?" is no.
