To work out the hcf of two numbers, you first need to break them down into their prime factors. In this case you'd get:
54 = 2x3x3x3
96 = 2x2x2x2x2x3
The next step is to identify any common prime factors. In this case, both numbers have a 2 and a 3 as prime factors. Multiply these together and you get 6. Therefore the HCF of 54 and 96 is 6.
HCF(96, 180) = 12
The GCF/HCF of 54 and 504 is 18.
The HCF of 16 and 96 is 16
The GCF is 18.
It is: 96
It is: 96
The HCF is 18
HCF is the highest common factor of two or more numbers. HCF of 12 and 54 is 6.
