Question

Reena has 246 plants to plant what is the maximum number of rows can she plant so that each row contains equal number of plants and their is no extra plant left

Answer 1

We write down the prime factors of the given number.

246 = 2 × 3 × 41

We have 6 and 41

We want the maximum rows so we take the largest number to be the rows.

So we will have 41 rows each made up 6 plants.

In this kind of question we must always get the prime factors of the number.

And since we need the maximum rows we use the largest number.
