Question

What is the number $x$?
I. The L.C.M of $x$ and $18$ is $36$.
II. The H.C.F of $x$ and $18$ is $2$.

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is D $4$

$x=L.C.M\times H.C.F=\text{First number}\times \text{Second number}$
Hence, required number $=\frac{36\times 2}{18}=4$
