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 hcf of 45 and 40 is 5.
