x + (-12) = 28 So x = 28 + 12 = 40
The GCF is 14.
28 and 56 have a GCF of 28.
4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48
The greatest common factor of 40 and 63 is 1.
The GCF is 4.
The GCF is 4.
The GCF is 4.
The GCF is 4.
The GCF is 4.
The GCF is 4.
The GCF of 12, 4, and 28 is 4.
4
The GCF is 4.
12 = 1,2,3,4,6, 28 = 1,4,7 So the greatest common factor is
GCF(4412, 28) = 4.
16 = (2)(2)(2)(2)28 = (2)(2)(7)40 = (2)(2)(2)(5)(2)(2) = 4
