To find the HCF of two numbers you first need to express them as the product of their prime factors: 12 = 2x2x3 60 = 2x2x3x5 The next step is to identify any common factors. In this case, both numbers have two 2s and a 3 as prime factors. Multiply these together and you get 2x2x3=12 Thus the HCF of 12 and 60 is 12.
12 and 24!
17 and 5
60 + 12 = 72 60 - 12 = 48 The two numbers are therefore 60 and 12.
You cannot. The numbers 2 and 12 have hcf = 2 and LCM = 12 The numbers 4 and 6 also have hcf = 2 and LCM = 12 So if you just knew the hcf and LCM you would not know which of the two was the required pair.
HCF is the highest common factor of two or more numbers. HCF of 12 and 54 is 6.

You need at least two numbers to find a GCF.
