Here we will show you two different methods you can use to determine if 7 is a factor of 49.
The first method entails simply listing all factors of 49 and then seeing if 7 is one of them. The factors of 49 are 1, 7, and 49. Looking at the list, you see that 7 is on the list, and the answer to "Is 7 a factor of 49?" is therefore yes.
For the second and perhaps easier method, we divide 49 by 7 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 7 is a factor of 49. If the quotient is a fractional number, then 7 is not a factor of 49.
49 divided by 7 is 7 which is a whole number. Thus, once again, the answer to "Is 7 a factor of 49?" is yes.
