Question

The LCM and HCF of 2 numbers are 168 and 6 respectively. If one of the numbers is 24, find the other?

• A. 36
• B. 38
• C. 40
• D. 42

Answer 1

Answer:

D. 42

We know that,

product of two numbers = $L.C.M\times{H.C.F of those numbers}$

Let the second number be x.

$24\times{x} = 168\times{6}$

$x = 6\times{7}$

X = 42.
