Answer:

To find the highest common factor (HCF) of two numbers when you already know their least common multiple (LCM), you can use the relationship between HCF and LCM:

HCF × LCM = Product of the two numbers

In this case, the product of 24 and 36 is 24 × 36 = 864.

So, HCF × 72 = 864

Divide 864 by 72 to find the HCF:

HCF = 864 / 72 = 12

Therefore, the HCF of 24 and 36 is 12.
