Question

The LCM of two numbers $525$ and $945$ is $4725$. Find their HCF

Answer 1

Let's find the HCF of given numbers.

$LCM\times HCF=Productoftwonumbers$

i.e.,

$\begin{array}{rcl}4725\times HCF& =& 525\times 945\\ & \Rightarrow & HCF=\frac{525\times 945}{4725}\\ & =& 105\end{array}$

Hence, the HCF is $105$
