Question

Find the smallest square number that is divisible by each of the numbers 18, 20, 24 and 27.​

Answer 1

Answer:

L.c.m of 18,20,24 and 27 is 1080.But, 1080 is not perfect.

So, 1080 = 2×2×2×3×3×3×5

To make it as a perfect square we have to multiply 2×3×5.

so 2×2×2×2×3×3×3×3×5×5 = 32400 which is divisible by all above numbers.
