Question

The product of two numbers is 30. If their HCF is 5, then LCM is

• A. 5
• B. 6
• C. 4
• D. 8

Answer 1

The Correct Option is B

Correct answer: 6

Explanation: 
We use the identity:
$\text{HCF} \times \text{LCM} = \text{Product of the two numbers}$

Given:
HCF = 5
Product = 30

So,
$\text{LCM} = \frac{30}{5} = 6$

Hence, the LCM is 6.
