LCM of two numbers is 936. If their HCF is 4 and one of the numbers is 72, the other is

A. 42

B. 52

C. 62

D. None of these

Answer: Option B

Solution(By Examveda Team)

Let two numbers be N₁ and N₂.
Now, we have
HCF of the numbers × LCM of the numbers = Multiplication of the numbers.
936 × 4 = 72 × N₁
Or, N₁ = $$\frac{{936 \times 4}}{{72}}$$
Or, N₁ = 52
