To find the HCF of 12 and 16, you first express them as the product of their prime factors:
12 = 2x2x3
16 = 2x2x2x2
The next step is to identify any common prime factors. In this case both numbers have two 2s as prime factors. Multiply these together and you get 4. Therefore the HCF of 12 and 16 is 4.
The HCF is 4. 16/4 is 4, 12/4 is 3
4
Since 12 is a factor of 24, it is automatically the GCF.
the hcf of 12 and 20 = 4
If you mean 12, 16 and 28 then the HCF is 4
The HCF of 16 & 33 is... 1
The GCF is 16.
The HCF of 16 and 96 is 16
The HCF of 12 and 60 is 12
The GCF is 12.
12 = 2 x 2 x 3 16 = 2 x 2 x 2 x 2 HCF=2 x 2 = 4 HCF = 4
The GCF is 2.
