Question

find the least square no which is exactly divisible by each of the no 8,12,15and20​

Answer 1

Answer:

3600

Step-by-step explanation:

The required solution of the problem is  

Let find the LCM of the given numbers i.e. 8,12,15and20

That is,  

2×2×2×5×3=120

But, 2,3,5 are not in pair so

multiply these with LCM

=120×3×5×2

=3600

Therefore there are 3600 numbers.
