The answer is 7. 7 x 3 = 21 7 x 7 = 49
The GCF is 7.
The greatest common factor of 14, 21 and 49 is 7.
The factors of 21 and 1,3,7, and 21Now since 21 is not a factor of 49, but 7 is we can say right away the GCF is 7.
The GCF of 21, 49 and 115 is 1.
7 is the greatest common factor of 4942 and 21, or of 49, 42 and 21, if that is what you meant.
7
Factors or 21 are: 1 3 7 21 Factors or 49 are: 1 7 49 Common factors of 21 and 49 are: 1 and 7
The greatest common factor of 7, 35 and 49 is 7.
The greatest common factor of 21 and 49 is 7.21 = 3 x 7, 49 = 7 x 7 so GCF = 7.
7
It is: 1
It is: 7
