Question

The product of two numbers is $432$ and their $L.C.M.$ is $72.$ Find their $H.C.F.$

Answer 1

Step: Find the $H.C.F.$

Given: Product of two numbers $=432$
$L.C.M.=72$
We know that.
Product of two numbers $=H.C.F.\times L.C.M.$
$\therefore 432=H.C.F.\times 72$
$H.C.F.=\frac{432}{72}$
$=6$
Hence, the $H.C.F.$ is $6$.
