Number 1Number 2(Optional) Enter Number 3

Determine the Greatest Common Factor (GCF) of (80,48)

Determine the factors for 80 up to 48 since that is the minimum of the 2 numbers
1,2,4,5,8,10,16,20,40

Determine the factors for 48 up to 48 since that is the minimum of the 2 numbers
1,2,3,4,6,8,12,16,24,48

The common factors between them are 1,2,4,8,16
The greatest common factor between them is 16
Since the Greatest Common Factor of both numbers ≠ 1, the numbers are not relatively prime (co-prime)
Since the Greatest Common Factor of Both Numbers is both ≠ 1 and have a difference of two, the numbers are not twin prime
