The sum of LCM and HCF of two numbers is 536 and the difference between LCM and HCF is 296. If one of the numbers is 104, then what is the other number?

  1. A. 420
  2. B. 480
  3. C. 484
  4. D. 506

Correct Answer: B. 480

Explanation

Solving L + H = 536 and L - H = 296 gives L = 416 and H = 120. Using the property LCM \times HCF = a \times b, we have 416 \times 120 = 104 \times b \implies b = 480.
