Question

The LCM and HCF of two numbers are 120 and 12 respectively. If one of the numbers is 24, find the other number.

• A. 60
• B. 30
• C. 40
• D. 120

Answer 1

The correct option is A 60

Given, LCM $=\text{120}$ , HCF $=\text{12}$ and one number$=24$

Let the second number be x.

We know that,

Product of two numbers = HCF $\times$ LCM.

Then,
$24\times x=120\times 12$
x = $\frac{120\times 12}{24}=60$

Hence, the other number is $60$.
