A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.
One way to determine the greatest common factor is to find all the factors of the numbers and compare them.
The factors of 15 are 1, 3, 5, and 15.
The factors of 17 are 1 and 17
The only common factor is 1. Therefore, the greatest common factor is 1.
