A common factor is '7'
3 x 7 = 21
7 x 7 = 49
'7' appears in both multiples.
LCM: 147 GCD: 7
The common factors are 1 and 7.
They are 1 and 7
The common factors are 1 and 7.
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, 35, and 49 is 7.The GCF is 7.Factors of 21: 1, 3, 7, 21Factors of 35: 1, 5, 7, 35Factors of 49: 1, 7, 49GCF (21, 35, 49) = 7
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 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.
