Question

The HCF of two numbers is $150$ and their LCM is $2088$. If one number is $720$, then the other number is

• A. $157$
• B. $300$
• C. $221$
• D. $435$

Answer 1

The correct option is D $435$

$LCM\times HCF=$ product of numbers
$2088\times 150=720\times x$
$313200=720x$
$x=\frac{313200}{720}=435$
Therefore, $D$ is the correct answer.
