GCF of 24 and 120

Number 1Number 2(Optional) Enter Number 3

Determine the Greatest Common Factor (GCF) of (24,120)

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

Determine the factors for 120 up to 24 since that is the minimum of the 2 numbers
1,2,3,4,5,6,8,10,12,15,20,24

The common factors between them are 1,2,3,4,6,8,12,24
The greatest common factor between them is 24
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
