Question
What is the smallest number that is divisible by both 18
and 24 and is greater than 200?Solution
The least common multiple (LCM) of 18 and 24 is calculated as: 18 = 2 × 3², 24 = 2³ × 3 → LCM = 2³ × 3² = 72. The smallest number divisible by 72 that is greater than 200 is: 72 × 3 = 216. Correct answer: a) 216
