Question

if LCM (p,q)=720, HCF(p,q)=5 p= 45 then q=?​

Answer 1

Value of $q = 80$

Explanation:

Given,

LCM of $p$ and $q$ $= 720$

HCF of $p$ and $q$ $= 45$

$p = 45$

As we know that,  

$\textrm{Multiplication of two number} = LCM \times HCF$

$45\times q = 720 \times 5$

$q = \frac{720 \times 5}{45}$

Value of $q = 80$ .
