Answer:

I will give you a simple method to do it.

Always remember, LCM is always divisible by HCF.

So, divide LCM/HCF = 72/6 = 12

Now, find factors of 12 such that their common factor is only one i.e. find the co-prime factors of 12.

Factors of 12 = 1 x 12, 2 x 6, 3 x 4

Here, the only co-prime pair is 3,4

Now multiply the numbers by their HCF.

Therefore, 3 x 6 = 18 and 4 x 6 = 24.

The two numbers are 18 and 24.

Step-by-step explanation:

salamat.
