To find the HCF of two numbers, you first have to express them as the product of their prime factors. In this case we have:
6 = 2x3
90 = 2x3x3x5
The next step is to identify any common factors. In this case both numbers have a 2 and a 3 as a prime factor. Multiply these and you get 6. Thus the HCF of 6 and 90 is 6.
hcf(6, 90) = 6.
6
The GCF is 6.
The GCF is 6.
It should be 6
The GCF/HCF of 12 and 90 is 6.
The GCF is 6.
The Highest Common Factor is 6
The HCF of 4 and 90 is 2.
The HCF would be 6
The GCF is 18.
The GCF is 30.
