To find the HCF of two numbers you first need to write them as the product of their prime factors:
36 = 2x2x3x3
40 = 2x2x2x5
The next step is to identify any common prime factors. In this case, both numbers have two 2s as prime factors. Multiplying these together gives 4. Therefore, the HCF of 36 and 40 is 4.
HCF(40, 36) = 4
The HCF (or GCF, greatest common factor) of two numbers can never be greater than the difference between the number
