What is the smallest perfect square that exactly divides the numbers 8, 12, and 18?

Explanation

First, find the least common multiple (LCM) of 8, 12, and 18, which is 72. The smallest perfect square multiple of 72 is 144 (since 72 × 2 = 144, and 144 is a perfect square). Therefore, 144 is the smallest perfect square that divides all three numbers.
