To find the HCF of two numbers you first need to express them as the product of their prime factors. In this case you'd get:
45 = 3x3x5
60 = 2x2x3x5
The next step is to identify any common prime factors. In this case both numbers have a 3 and a 5 as a prime factor. Multiplying these together gives:
3x5 = 15
And so 15 is the HCF of 45 and 60.

The GCF is 10.
HCF is the highest common factor of two or more numbers. One such pair which has 60 as their HCF can be: 120 and 180.
The GCF is 12.
The GCF is 12.
The HCF of 60 is 60. But it's a factor as opposed to a common factor because there's only one number.
