To calculate the GCF you first need to split the numbers into their prime factors:
16=2x2x2x2
32=2x2x2x2x2
The next step is to identify the common factors in each. Both numbers use four 2s, so we take these 4 2s and work out the product:
2x2x2x2=16
Thus, the GCF of 16 and 32 is 16.
No, 32 is a multiple of 16. 16 is a factor of 32.
4
No, 18 is not a factor of 32.
The GCF is 32.
It is 4
The GCF is 16.
8
The GFC of 32 and 40 is 8.
The GCF is 1.
The GCF is 1.
You probably mean GCF (Greatest Common Factor), and the answer is 4.
