Sol; To find least perfect square number which is divisible by 3, 4, 5, 6 and 8. LCM (3, 4, 5, 6 ,8) = 120 120 = 2 x 2 x 2 x 3 x 5. As 2,3 and 5 are not in pair in LCM’s factor so we need to multiply 120 by 5 and 3,2 to make it a perfect square. 120 x 2 x 5 x 3 = 3,600. ∴ 3600 is the least perfect square divisible by 3, 4, 5, 6 and 8.
