Q. The LCM of two numbers is 520 and their HCF is 4. If one of the number is 52, then the other number is :
Answer: 40
Notes: ∵ First Number $latex \times$ Second Number = HCF $latex \times$ LCM => 52 $latex \times$ Second Number = 4 $latex \times$ 520 $latex => Second\ Number\ = \frac{4\times 520}{52} = 40&s=1$ Hence option [A] is correct answer.
