Question

The HCF and LCM of two numbers are $9$ and $360$ respectively. If one number is $45$, find the other number.

Answer 1

We know that

HCF$\times$LCM=product of two numbers

Given that HCF$=9$ and LCM$=360$

One number$=45$ Let second no. be x

$9\times 360=45\times x$

$x=\frac{9\times 360}{45}=9\times 8=72$

$\therefore$Other number$=72$
