the factors of 21 are 3,7,1, 21,and -1, -21,-3,-7. the factors of 49 are 1,49,7,7 and -1, -21-7-7.
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 greatest common factor of 14, 21 and 49 is 7.
The GCF is 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 GCF of 21, 49 and 115 is 1.
The GCF is 7.
The answer is 7. 7 x 3 = 21 7 x 7 = 49
The GCF is 7.
7
The factors of 21 are 1, 3, 7, 21 The factors of 49 are 1, 7, 49 The largest matching number is 7 so 7 is the GCF of 21 and 49.
7 is the greatest common factor of 4942 and 21, or of 49, 42 and 21, if that is what you meant.
7 (7 x 3= 21, 7 x 7=49)
