If HCF(456, 96) = 24 and LCM(456, 96) = 4 × k, then the value of k is:
A 456
B 912
C 457
D 10944
Correct answer: A — 456
- HCF × LCM = product of the two numbers, so LCM = • 1824 = 4 × k, so k = 1824 ÷ 4 = 456.
- Why the other options are wrong:
- B (912): The LCM was doubled by mistake.
- C (457): A slip when dividing the LCM.
- D (10944): That uses HCF × k, but the relation is HCF × LCM = product of the numbers.
The product of two numbers equals the product of their HCF and LCM.
