Answer 2

Given:

saplings that can be arranged in rows of 12,15,or40 in each row

To find:

Least number of the saplings that can be arranged

Solution:

As we have given in the question that we have to arrange 12, 15, or 40 saplings in each row.

In this case, we ahve to find the LCM of the given numbers.

• LCM [ 12, 15, 40]

here we will find the LCM by the prime factorization method;

• 12 = 1×2×2×3
• 15 = 1×3×5
• 40 = 1×2×2×2×5
• LCM [12, 15, 40] = 1×2×2×2×3×5
• LCM [12, 15, 40]= 120

so

we need at least 120 sappling to arrange this in the row of 12, 15 or 40
