Answer 2

Answer:

3600

Step-by-step explanation:

first we take LCM of 8,12,15,20 that is 120

now find the prime factors of 120 that is 2×2×2×3×5

by grouping this number we can find that 2,3,5is not forming a pair of like factors so multiply the 2,3,5 that is 30

therefore we multiply 120 by 30 that is 3600

hence,3600is the least square which is exactly divisible by 8,12,15,20
