What is the greatest common factor of 17 and 50?

Answer 1

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.

The greatest common factor of 5670 and 12150 is 810

Answer 2

Convert each number into its prime factors.

56 = 2 x 2 x 2 x 7 = 23 x 7

567 = 3 x 3 x 3 x 3 x 7 = 34 x 7

The only factor in common and therefore the Greatest Common Factor is 7.

Answer 3

First, split the values up into their basic factors:

55 = 5 * 11

121 = 11 * 11

Now you can see that the greatest common factor is 11.
