Is 20 a factor of 780?

Here we will show you two different methods you can use to determine if 20 is a factor of 780.

The first method entails simply listing all factors of 780 and then seeing if 20 is one of them. The factors of 780 are 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, and 780. Looking at the list, you see that 20 is on the list, and the answer to "Is 20 a factor of 780?" is therefore yes.

For the second and perhaps easier method, we divide 780 by 20 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 20 is a factor of 780. If the quotient is a fractional number, then 20 is not a factor of 780.

780 divided by 20 is 39 which is a whole number. Thus, once again, the answer to "Is 20 a factor of 780?" is yes.
