Answer 1

Answer:

ஃ The least no. exactly divisible by 8, 12, 15, 20 = 120

Step-by-step explanation:

To find that, do LCM

2 | 8, 12, 15, 20

2 | 4, 6, 15, 10

2 | 2, 3, 15, 5

3 | 1, 3, 15, 5

5 | 1, 1, 5, 5

1, 1, 1, 1

LCM of 8, 12, 15, 20 = 2 × 2 × 2 × 3 × 5 = 120

Answer 2

The value of LCM of 8, 12, 15, and 20 is the smallest common multiple of 8, 12, 15, and 20. The number satisfying the given condition is 120. ∴LCM(8, 12, 15, 20) = 120.
