The GCF of 3 and 21 is: 3
3: (3 x -1) and (3 x -7)
The GCF is 3.
greatest common factor of 21 and 3 is 3.
3
The greatest common factor of 21 and 75 is 3.
The greatest commonfactor(gcf) of 24 and 21 is 3
The common factors of 21 and 42 are 3, 7 and 21. The greatest common factor (GCF) is 21.
The greatest common factor of 6 and 21 is 3.
The greatest common factor of 21 and 33 is 3. The factors of 21 are 1,3,7,21 and the factors of 33 are 1,3,11 and 33 so the GCF is 3
The Greatest Common Factor of 60, 21, 9: 3
The greatest common factor of 21 and 75 is 3.
The Greatest Common Factor of 21, 9 is 3.
The greatest common factor of 21 and 162 is 3.
The greatest common factor of 21 and 102 is 3.
The GCF is 3.
The greatest common factor of 21, 36, and 60 is 3
The greatest commonfactor(gcf) of 24 and 21 is 3
The Greatest Common Factor (GCF) is: 3.
The greatest common factor (GCF) is 3.
3 is the greatest common factor of 21, 27, and 51The GCF is 3.
The factors of the two numbers are :- 51 : 1, 3, 17 and 51 21 : 1, 3, 7 and 21. Ignoring the trivial factor of 1, the only common factor and therefore the greatest common factor is 3.
