Question

What the least number which is a perfect square and exactly divisible by
18, 24 and 36.​

Answer 1

144

Explanation:

The answer is 144 because we can take any multiple of 72, the LCM of 18, 24, and 36, but 72 is not a perfect square. So, we go to the next multiple, 144, which is a perfect square, so the answer is 144. Hope it helps!
