Question

What is the least perfect square number divisible by 3, 4, 5, 6 and 8.​

Answer 1

First find the lcm

lcm of 3, 4, 5, 6 and 8 = 120

120 = 2 x 2 x 2 x 3 x 5

as we can see 2, 3, and 5 are not in pairs so we've to multiply it by the stated number that is 120

⇒120 x 2 x 5 x 3 = 3,600

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

Answer 2

Step-by-step explanation:

taking the LCM of 3,4,5,6, and 8 =120

Also , 120 =2×2×2×3×5 in which 2 , 3 and 5 are not in pair

So, 120 should be multiplied by 2 ,3, and 5 to get a perfect square

The required least square number is 120×2×3×5=3600.
