B Correct answer
Explanation

HCF * LCM = Product of two numbers. 28 * 336 = 112 * x. x = (28 * 336) / 112 = 336 / 4 = 84.

AI explanation

The product of two numbers equals the product of their HCF and LCM. Let the other number be x, giving the equation 112 * x = 28 * 336. Solving for x gives x = (28 * 336) / 112, which simplifies to 84.
