The product of two numbers is 48 and their HCF is 4. What is their LCM?
A
12
B
16
C
24
D
48
Correct Answer: Option A — 12
Explanation:
LCM × HCF = Product of the two numbers. LCM = 48 ÷ 4 = 12. This important formula is frequently tested in competitive exams. It allows rapid calculation of LCM or HCF when the product and one factor are known making it a key shortcut for number theory problems in timed exam conditions.
