if 2 positive integers are reltively prime to each other and the product if these two integers is 240,then what is L.C.M of these 2 integers?

I guess relatively prime is same as co-prime

For co-prime, HCF is 1

the numbers will be (1, 240)

So LCM is 240.

is that correct?

yeah you are correct, but why cannot the numbers may be (16, 15) or something?

The product of two positive integers that are relatively prime to each other is actually the LCM of the two positive integers.
