A single number cannot have a greatest common factor. It is determined by the factors of two or more numbers. The Greatest Common Factor (GCF) is the largest factor common to two or more numbers. If that's 2 and 8, the GCF is 2.
For example, 17 is the GCF of 34, 51, and 102 because it is the largest number that is a factor common to all three numbers.
