Here's a good method to quickly find GCFs:
(1) Replace the larger number with the difference of the two numbers.
(2) If the two new numbers are the same, then that gives the GCF. Otherwise repeat step (1) on the new numbers.
With 64 and 32:
(64,32) -> (32,32) (64 has been replaced with 32 since 64-32=32)
The two numbers are now the same, so the answer is 32.
The LCM is: 960 The GCF is: 8

LCM of 10 32 64 80 is 320.
A = LW 64 = 64 * 1 or 1 * 64 64= 32 * 2 or 2 * 32 64 = 16 * 4 or 4 * 16
4
GCF(64, 96) = 32
The GCF is 16.
The GCF is 16.
No, the GCF of 32 and 64 is 32.
The answer is 32
The GCF is 8.
The GCF is 32.
The greatest common factor of the numbers 192, 96 and 64 is 32.
32 and 64
The GCF is 4.
The GCF is 32.
The GCF is 1.
