Number 1Number 2(Optional) Enter Number 3

Determine the Greatest Common Factor (GCF) of (35,84)

Determine the factors for 35 up to 35 since that is the minimum of the 2 numbers
1,5,7,35

Determine the factors for 84 up to 35 since that is the minimum of the 2 numbers
1,2,3,4,6,7,12,14,21,28

The common factors between them are 1,7
The greatest common factor between them is 7
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
