The greatest common factor of 21 and 56 is 7.
The greatest, (Highest) Common Factor of 21 and 56 is 7
7. 7x3=21 7x8=56
The GCF of 21, 56, and 70 is 7.
Find a common factor of 21 and 56 and divide both by that factor to give two new numbers. If necessary, repeat the process with a common factor of these two numbers and so on. This looping can be done in one step if you can find the greatest common factor. So, for 21 and 56, the GCF = 7 So 21/56 = (21/7) / (56/7) = 3/8
The Greatest Common Factor (GCF) is: 7
