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 of 40 & 12 is... 4
The HCF is 4. 16/4 is 4, 12/4 is 3
the hcf of 12 and 20 = 4
It is: 4
