Question

The product of two numbers is $882$ and their LCM is $126$. What is the HCF of these numbers?

Answer 1

Given that:

Product of two numbers$=882$

$LCM$ of the same numbers$=126$

$HCF=?$

Since we know that,

$HCF\times LCM=$ Product of the numbers

$HCF\times 126=882$

$HCF=\frac{882}{126}$

$HCF=7$.

Hence, the HCF is $7$.
