Is 28 a factor of 280?

Here we will show you two different methods you can use to determine if 28 is a factor of 280.

The first method entails simply listing all factors of 280 and then seeing if 28 is one of them. The factors of 280 are 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, and 280. Looking at the list, you see that 28 is on the list, and the answer to "Is 28 a factor of 280?" is therefore yes.

For the second and perhaps easier method, we divide 280 by 28 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 28 is a factor of 280. If the quotient is a fractional number, then 28 is not a factor of 280.

280 divided by 28 is 10 which is a whole number. Thus, once again, the answer to "Is 28 a factor of 280?" is yes.
