Question

Determine whether LCM of two relatively prime or co-prime numbers is the product of both numbers?

• A. Yes.
• B. No.
• C. Cannot be determined.

Answer 1

The correct option is A Yes.

Yes, the LCM of two relatively prime or co-prime numbers is the product of both numbers.
For example: by determining the LCM of $15$ and $8$ we get,


LCM of $15$ and $8$ $=2\times 2\times 2\times 3\times 5$
$=8\times 15=120$.

We also know that both are co-prime numbers because they do not have any common prime factors.

So, the statement in the question is justified.
