lcm(9, 12) = 36; hcf(9, 12) = 3.
HCF(9, 12) = 3
The HCF of 12 and 60 is 12
The GCF is 12.
3.
You need at least two numbers to find a GCF.
The GCF is 2.
The HCF of 40 & 12 is... 4
The hcf of 12 & 36 is 12
the HCF is 6
First, write both numbers as the product of their prime factors: 9 = 3x3 12 = 2x2x3 The next step is to identify any common prime factors. In this case, both numbers have 3 as a prime factor. Therefore, the HCF of 9 and 12 is 3.
The GCF is 9.
