Question

the least number,which is perfect square and is divisible by each 16,20,and 24 is answer with full soulution

Answer 1

First we will calculate the LCM by Prime Factorisation.
16 = 2x2x2x2
20 = 2x2x5
24 = 2x2x2x3
LCM = 2x2x2x2x3x5
For the no. to be perfect square, it must have each no. in pair of two.
No= 2x2x2x2x3x3x5x5
= 3600

Answer 2

Answer:3600

Step-by-step explanation:

LCM of 16 , 20 ,24 is 240

Then for making it perfect square we have to multiply it with such no which is divisible by 16, 20 and 14

So

Will multiply 3 & 5 with 240 to make it perfect square.

Therefore,

240*3*15=3600

Which is a perfect square and also a least no. which is divisible by 16,20,and24
