Question

The LCM of 4 numbers is 117 and the HCF of each pair is 3, find the multiplication of all thenumbers?

Answer 1

117 has factors 3,9,39,117,1,13

Now, we have to make groups of 4 with Hcf of each pair 3!

So, we need to choose from 3,9,39,117 as 3 does not divide 13.

The possible groups:

3,3,9,39

3,3,3,117

3,3,9,39

Now, you can have the products!
