The GCF is 1.
The greatest common factor of 20, 8, and 5 is 1. (5 only has two factors: 1 and 5, and 5 is not a factor of 8.)
The greatest common factor -- in fact, the only common factor -- of 2, 5, and 8 is the number 1.

It is one
The GCF of 5 and 8 is 1. 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 5 are 1 and 5. The factors of 8 are 1, 2, 4, and 8 The only common factor is 1. Therefore, the greatest common factor is 1.
The GCF of 5, 8 and 12 is 1.
GCF(5, 10, 8) = 1
8 is the greatest common factor of 40 and 48. 8 X 5 = 40 and 8 X 6 = 48.
