7 and 1
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 factors of 21 are:1, 3, 7, 21The factors of 49 are:1, 7, 49The common factors are:1, 7
21- 1,3,7,29 49- 1,7,49
The factors of 21 are:1, 3, 7, 21The factors of 49 are:1, 7, 49The common factors are: 1, 7The Greatest Common Factor (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.
The factors of 14 are: 1, 2, 7, 14The factors of 21 are: 1, 3, 7, 21The factors of 49 are: 1, 7, 49The common factors are: 1, 7
1 and 7
Factors for 147: 1, 3, 7, 21, 49, 147 Factors for 294: 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294 Common Factors: 1, 3, 7, 21, 49, 147
The GCF is 7.
Do you mean, what are the common factors of 49, 21, and 91? Only 7 (and 1, of course) is a common factor for those numbers. Individually, 49's factors are 1, 7 and itself. 21's factors are 1, 3, 7, and itself. 91's factors are 1, 7, 13, and itself.
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.
