Question

The HCF of two numbers is 12 and their LCM is 144. If one number is 36, the other number is:

• A. 48
• B. 60
• C. 24
• D. 72

Answer 1

The Correct Option is A

Step 1: Product of numbers \(= \text{HCF}\times\text{LCM} = 12\times144 = 1728\).
Step 2: Other number \(= \dfrac{1728}{36} = 48\).

Quick Tip: \(\text{Number}_1 \times \text{Number}_2 = \text{HCF}\times\text{LCM}\).
