Is 49 a factor of 644?

Here we will show you two different methods you can use to determine if 49 is a factor of 644.

The first method entails simply listing all factors of 644 and then seeing if 49 is one of them. The factors of 644 are 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, and 644. Looking at the list, you see that 49 is not on the list, and the answer to "Is 49 a factor of 644?" is therefore no.

For the second and perhaps easier method, we divide 644 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 644. If the quotient is a fractional number, then 49 is not a factor of 644.

644 divided by 49 is 13.14285714 which is a fractional number. Thus, once again, the answer to "Is 49 a factor of 644?" is no.
