Answer :
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) [tex] 5,21 [/tex]
[tex] LCM=5*21\\ LCM=105 [/tex]
in this case the LCM of two numbers is the product of the two numbers
2) [tex] 8,10 [/tex]
[tex] 8=2^{3} \\ 10=2*5 [/tex]
[tex] LCM=2^{3}*5\\ LCM=40 [/tex]
in this case the LCM of two numbers is not the product of the two numbers
therefore
the answer is
Sometimes
