Explanation: āœ… Correct Answer: D. 337 šŸ“š Explanation: We first find the Least Common Multiple (LCM) of 12, 16, and 28, which is 336. This is the smallest number divisible by all three. Since the question states that the difference after subtracting 1 must be divisible, we add 1 to the LCM. The result is 336 + 1 = 337.
