Question

The Least Common Multiple of two relatively prime numbers $x$ and $y$ is equal to

• A. $x+y$
• B. 2($x+y$)
• C. $x\times y$
• D. $2\times x\times y$

Answer 1

The correct option is C $x\times y$

Given that $x$ and $y$ are relatively prime numbers.
therefore, $x$ and $y$ have no common factor between them other than 1.
so, Least common multiple of both the numbers would be $x\times y$.
For example: 5 and 7 are relatively prime numbers so LCM of both these numbers is $5\times 7$ = 35 .
