Question

find the least number which is a perfect square and which divisible by 12,15,and24​

Answer 1

Answer:

First we need to find LCM of 12,15&24

LCM(12,15,24)= 2×2×2×3×5 = 120

Then 2,3&5 are not in pairs so we need to multiply 2×3×5 = 30

i.e. 120×30

= 3600

So, least perfect square number which is divisible by 12,15 & 24 is 3600

Answer 2

Answer:

Divisible by 12, 15 and 24 First we should find LCM of 12,15,24

LCM= 2,2,2,3,5=120

Then,

As they are not in pair, we need to multiply the LCM with 2, 3,5=30

i.e 120×30=3600

therefore least number which is divisible by 12,15,24 is 3600
