Write the $L C M$ of $p$ and $q$ if $p$ and $q$ are co primes.

Open in App

Solution

Given,
$p$ and $q$ are co-prime number
So it's common factor is $1$
So $H C F (q, q) = 1$
To find the $L C M$ we know that
Product of two number $= H C F \times L C M$
$p \times q = 1 \times L C M$
$L C M = p \times q$
