To find the GCF of 32 and 36 you first have to break them down into their prime factors:
32 = 2x2x2x2x2
36 = 2x2x3x3
The next step is to identify any common factors. In this case both numbers have two 2s as prime factors. To find the GCF you just multiply these numbers together:
2x2 = 4
And so the GCF of 32 and 36 is 4.
The GCF is 16.
The GCF is 4.
The GCF is 16.
The GCF is 16.
The GCF is 36.
The GCF is 6.
