Question

If $HCF$ of two numbers is $27$ and then $LCM$ is $162$. If one of numbers is $54$, find the other.

Answer 1

Let $x,y$ be the two numbers

Given that

$x=81$

$HCF=27$ and $LCM=162$

We know that the product of two number$=HCF\times LCM$

Implies that

$x\times y=27\times 162$

$81\times y=4374$

$y=\frac{4374}{81}=54$
