Question

The LCM of two numbers is $2079$ and their HCF is $27$. If the first number is $189$, then the second number is

• A. $295$
• B. $296$
• C. $297$
• D. None of the above

Answer 1

Answer: (C)

$297$

Product of two numbers $=HCF\times LCM$

$\Rightarrow 189\times \text{2nd number}=2079\times 27$

$\Rightarrow \text{2nd number}=\frac{2079\times 27}{189}=297$.

So, option $C$ is correct.
