Is 3 a factor of 345?

Here we will show you two different methods you can use to determine if 3 is a factor of 345.

The first method entails simply listing all factors of 345 and then seeing if 3 is one of them. The factors of 345 are 1, 3, 5, 15, 23, 69, 115, and 345. Looking at the list, you see that 3 is on the list, and the answer to "Is 3 a factor of 345?" is therefore yes.

For the second and perhaps easier method, we divide 345 by 3 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 3 is a factor of 345. If the quotient is a fractional number, then 3 is not a factor of 345.

345 divided by 3 is 115 which is a whole number. Thus, once again, the answer to "Is 3 a factor of 345?" is yes.
