To find the gcf of 32 and 16 you first need to split them into their prime factors:
32 = 2x2x2x2x2
16 = 2x2x2x2
The next step is to identify any common prime factors. In this case both numbers have four 2s as prime factors, so we can multiply them together:
2x2x2x2 = 16
And so the GCF of 32 and 16 is 16.
The GCF is 2.
The GCF is 1.
The GCF is 1.
The GCF is 1.
The GCF is 4.
The GCF is 2.
The GCF is 8.
The GCF is 8.
The GCF is 8.
The LCM is 30. The GCF is 4.
Prime factorization of 24 = 2x2x2x3Prime factorization of 16 = 2x2x2x2GCF(24, 16) = 2x2x2 = 8
The GCF is 32.It is: 32It is: 32
