GCF requires a COMMON factor. You cannot have a COMMON factor with only one number - you require at least TWO numbers.

To have a greatest COMMON factor of 7, the numbers must have only 7 as a common prime factor.

Thus, for example 7, 12474, 3183837475 & 20106594977 have a Greatest COMMON factor of 7.

Any number that is a multiple of 7 will have a GCF of 7. For example, if you consider the numbers 14 and 21, both are multiples of 7 and their greatest common factor is 7.
