we know that
The Least Common Multiple (LCM) of two numbers is the product of the two numbers only when they are relatively prime.if two numbers share a common factor, then the LCM of two numbers is not the product of the two numbers.
Examples
1) \(5,21\)
\(LCM=5*21\\ LCM=105\)
in this case the LCM of two numbers is the product of the two numbers
2) \(8,10\)
\(8=2^{3} \\ 10=2*5\)
\(LCM=2^{3}*5\\ LCM=40\)
in this case the LCM of two numbers is not the product of the two numbers
therefore
the answer is
Sometimes
