Assertion (A): For two odd prime numbers x and y,(x ≠ y ), LCM (2 x, 4 y )=4 x y Reason (R): LCM (x, y ) is a multiple of HCF (x, y ).

Assertion (A) : For two odd prime numbers $\displaystyle x$ and $\displaystyle \mathrm{y},(x \neq \mathrm{y})$, $\displaystyle \operatorname{LCM}(2 x, 4 \mathrm{y})=4 x \mathrm{y}$ Reason (R) : $\displaystyle \operatorname{LCM}(x, \mathrm{y})$ is a multiple of $\displaystyle \operatorname{HCF}(x, \mathrm{y})$.
