leaves 12 and 45
Both are divisible by 3
leaves 4 and 15. These are not further divisible
2x3=6
2 x 3 x 3 x 5 = 90
2 x 2 x 5 x 5 = 100
2 x 2 x 2 x 3 x 3 x 5 x 5 = 1800, the LCM

The GCF is 6.
The greatest common denominator of any set of denominators is infinite.
It is: 2*3 which is 6
The GCF of 15 and 90 is 15.
GCF of 90 and 75 is 15.
The GCF of 24, 45, and 90 is 3.
The GCF of 24 and 90 is 6. 24/6 = 4 90/6 = 15 24/90 = 4/15
72 and 90 is 18, 24 and 96 is 24, so neither
The GCF is: 6
You need at least two numbers to find a GCF. If that's 24 and 90, the GCF is 6.
