315 = 32 x 5 x 7525 = 3 x 5 x 73 x 5 x 7 = 105 (GCF)
10 = 2 x 5 20 = 2 x 2 x 5 35 = 5 x 7 GCF = 5
The GCF is 2^3 x 5.
5 x 5 x 5 = 125 2 x 3 x 5 x 5 = 150 5 x 5 = 25, the GCF
GCF of 75 and 12075 = 5 x 5 x 3120 = 2 x 2 x 2 x 3 x 5GFC = 3 x 5 = 15
3 = 1 x 3 5 = 1 x 5 7 = 1 x 7 GCF = 1
75 = 3 x 5 x 5 140 = 2 x 2 x 5 x 7. GCF is thus 5.
