Determine the Greatest Common Factor (GCF) of (1000,100)

1,2,4,5,8,10,20,25,40,50,100

1,2,4,5,10,20,25,50,100

The common factors between them are 1,2,4,5,10,20,25,50,100

The greatest common factor between them is

Since the Greatest Common Factor of both numbers ≠ 1, the numbers are

Since the Greatest Common Factor of Both Numbers is both ≠ 1 and have a difference of two, the numbers are not twin prime
