GCF of 6 and 10

Number 1Number 2(Optional) Enter Number 3

Determine the Greatest Common Factor (GCF) of (6,10)

Determine the factors for 6 up to 6 since that is the minimum of the 2 numbers
1,2,3,6

Determine the factors for 10 up to 6 since that is the minimum of the 2 numbers
1,2,5

The common factors between them are 1,2
The greatest common factor between them is 2
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
