45 = 3 * 3 * 5 63 = 3 * 3 * 7 126 = 2 * 3 * 3 * 7 Gcf = 3 * 3 = 9 45/9 = 5 63 / 9 = 7 126 / 9 = 14
The GCF is 210.. I believe..so nevermind.
The GCF is 2^3 x 5.
21. 42 = 2 x 3 x 7 63 = 32 x 7 105 = 3 x 5 x 7 gcf = 3 x 7 = 21
Divide both by their GCF (5) and you will get 3/7.
The GCF is 1.
You need at least two numbers to find a GCF. If that's 3 and 15, the GCF is 3.
The GCF is 21.
The greatest common factor of 63 and 195 is 3.
50
35 = 5 x 7 105 = 5 x 7 x 3 175 = 5 x 7 x 5 gcf = 5 x 7 x 3 x 5 = 105 x 5 = 525
2 x 5 x 7 = 703 x 5 x 7 = 105Select the common factors.5 x 7 = 35, the GCF
15 + 35 = 5*(3 + 7).
105. 525 = 3 x 52 x 7 210 = 2 x 3 x 5 x 7 gcf = 3 x 5 x 7 = 105
45 = 3 * 3 * 5 63 = 3 * 3 * 7 126 = 2 * 3 * 3 * 7 Gcf = 3 * 3 = 9 45/9 = 5 63 / 9 = 7 126 / 9 = 14
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
The GCF is 210.. I believe..so nevermind.
