The greatest common factor of 21 and 49 is 7.21 = 3 x 7, 49 = 7 x 7 so GCF = 7.
The GCF is 7.
7 (7 x 3= 21, 7 x 7=49)
The GCF of 21, 49 and 63 is 7.The factors of 21 are: 1, 3, 7, 21The factors of 49 are: 1, 7, 49The factors of 63 are: 1, 3, 7, 9, 21, 63The common factors are: 1, 7The Greatest Common Factor (GCF) is: 7GCF = 7
The GCF is 7.
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.
The answer is 7. 7 x 3 = 21 7 x 7 = 49
The GCF is 7.
It is: 1
