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
TO work out the HCF you need to split the numbers into their prime factors. In this case you have: 40 = 2x2x2x5 48 = 2x2x2x2x3 The next step is to identify any common prime factors. Both numbers have three 2s as prime factors. Multiply these together and you get: 2x2x2 = 8 Thus the HCF of 40 and 48 is 8.
