Question

Find the least square number exactly divisible by each of the numbers 8, 12, 15, 20

Answer 1

Step-by-step explanation:

First we need to find the LCM of the given numbers i.e., 8,12,15 and 20

LCM= 2×2×2×5×3 = 120

Then

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

i.e., 120 × 30

So,

least perfect square number which is divisible by each of numbers 8,12,15, and 20

=120×30 = 3600
