Question

if the lcm of two numbers is 84and their product is 168.what is their hcf​

Answer 1

SOLUTION:-

Given:

•The L.C.M. of two numbers is 84.

•Their product is 168.

To find:

Their H.C.F.

Explanation:

We know that, Formula:

Product of two numbers= L.C.M× H.C.F

$= > 168 = 84 \times H.C.F. \\ \\ = > H.C.F.= \frac{168}{84} \\ \\ = > H.C.F= 2$

Thus,

The H.C.F is 2.
