​

Answer 1

Answer:

3600 is the correct answer

Step-by-step explanation:

First of all we have to take LCM of 8,12,18,40,45

which is equal to 360 .

Now Factorising 360 into its prime factors,

360 = 2 × 2 × 2 × 3 × 3 × 5

Now grouping them into pair

360 = (2 × 2) × (3 × 3) × 2 × 5

here 2 and 5 are not perfectly paired .To make 360 a perfect square , we have to multiply them with 2 × 5 i.e 10 .

The perfect square is 360 × 10 = 3600 .

So the least no. is 3600.
