The HCF of 16 and 20 is 4
4
The HCF is 4.
the hcf of 12 and 20 = 4
The GCF is 4.
If you mean 12, 16 and 28 then the HCF is 4
To find the hcf, first split the numbers into their prime factors: 20 = 2x2x5 16 = 2x2x2x2 The next step is to identify any common prime factors. In this case both numbers have 2 and 2 as prime factors. Multiply these together and you get 4. Thus the hcf of 20 and 16 is 4.
First you need to split the numbers down into their prime factors: 20 = 2x2x5 16 = 2x2x2x2 The next step is to identify any common factors. In this case, both numbers have two 2s as prime factors. Multiply these together and you get: 2x2 = 4 Thus the HCF of 20 and 16 is 4.
The HCF of 16 & 33 is... 1
The GCF is 28.
The GCF is 16.
