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 common factors and greatest common factor is to find all the factors of the numbers and compare them.

The factors of 85 are 1, 5, 17, and 85.

The factors of 115 are 1, 5, 23, and 115.

The common factors are 1 and 5. Therefore, the greatest common factor is 5.

The Greatest Common Factor (GCF) is: 5

The greatest common factor of 85 and 255 is 85.

The GCF is 5.

The greatest number which divides both 51 and 85 is 17. So, greatest common factor is 17.Alternate method:P.F. of 51 = 3x17P.F. of 85 = 5x17Clearly, from the P.F. of both numbers 17 is the greatest common factor.The GCF is 17.51 and 85's highest common factor is 17.
