The product of four consecutive numbers is always divisible by which of the following numbers?
Correct Answer: A. 24
Explanation: For a set of four consecutive integers, the product is always divisible by 24. This is because in any four consecutive numbers, at least two must be even (with one being a multiple of 4), and at least one must be a multiple of 3. Multiplying these factors (2 * 4 * 3) results in 24, which is the largest constant that consistently divides the product of any such sequence.
