7 is the greatest common factor of 4942 and 21, or of 49, 42 and 21, if that is what you meant.
The GCF (greatest common factor) would be 21.
21
The greatest common factor of 630 , 84 = 42
The GCF is 3.
The common factors of 21 and 42 are 3, 7 and 21. The greatest common factor (GCF) is 21.
21 itself is the greatest common integral factor, since 21 X 2 = 42.
Since 21 is a factor of 42, it is automatically the GCF.
7 is the greatest common factor of 4942 and 21, or of 49, 42 and 21, if that is what you meant.
