is greatest common factor prime?
16788
A common factor of two numbers is a factor that divides both numbers. The greatest common factor (GCF) of two numbers is the greatest number that divides both numbers. To find the GCF, take the prime factorization of both numbers. Then write down the factors that they have in common.

Since 1 divides into everything, then the greatest common factor in this case is just 1. When 1 is the GCF, the numbers are said to be "relatively" prime; that is, they are prime, relative to each other. Then the GCF is 1 and the LCM is 2 × 2 × 2 × 3 = 24.
