★find least perfect square divisible by 3,4,5,6 and 8.

_________________________________

◇Solution

→ L.C.M of 3,4,5,6,8 = 120

→ 120 = 2×2×2×3×5

★In the above factorization 2,3 and 5 are not in pairs so multiply it by the stated numbers.

→120×2×3×5 = 3600

→ 3600 is the least perfect square divisible by 3,4,5,6 and 8.
