The GCF is 1.
10 = 2 x 5 20 = 2 x 2 x 5 35 = 5 x 7 GCF = 5
140 = 2 x 70 = 2 x 5 x 14 = 2 x 2 x 5 x 7; 7 is the gcf.
2 x 5 x 7 = 703 x 5 x 7 = 105Select the common factors.5 x 7 = 35, the GCF
GCF of 35, 49, 5635 = 5 x 749 = 7 x 756 = 2 x 2 x 2 x 7The GCF = 7
2 x 2 x 5 = 20 5 x 7 = 35 The GCF is 5.
140=2*2*5*7 300=2*2*3*5*5 comon factrs are 2*2*5=20 20 is the gcf
You can't. You need at least two numbers to find a GCF.
5 x 7 = 35 2 x 2 x 2 x 7 = 56 The GCF is 7.
5 x 7 = 35 2 x 2 x 2 x 7 = 56 The GCF is 7.
75 = 3 x 5 x 5 140 = 2 x 2 x 5 x 7. GCF is thus 5.
The systematic way to get the answer is: 90 = 2*3*3*5 210 = 2*3*5*7 So gcf is 2*3*5 = 30
