Question

1. What is the least number of children that can be arranged
in rows of 12, 16 or 18 in each row?​

Answer 1

Heyy dear♥️

144 children can be arranged in a row of 12, 16 and 18.

EXPLANATION :

We have to find the least number of children. So let us find the LCM of 12, 16 and 18.

12 = 2 × 2 × 3

16 = 2 × 2 × 2 × 2

18 = 2 × 3 × 3

LCM = 2 × 2 × 2 × 2 × 3 × 3 = 144

Hence, 144 childrens can be arranged in a row of 12, 16 or 18.

Hope you got it :)
