Question

the least perfect square no : which is divisible by 3, 4, 5, 6 & 8 is:

Answer 1

Answer:

Step-by-step explanation:

Find the LCM thus

3  

4 = 2x2

5

6 = 2x3

LCM = 2x2x3x5 = 60.

You see, in the LCM 2 already squared while 3 and 5 are not.

So you need to multiply 60 by 3 and 5 to get 900 which is a perfect square and divisible by 3, 4, 5 and 6.
