Li Na is going to plant 636363 tomato plants and 818181 rhubarb plants. Li Na would like to plant the plants in rows where each row has the same number of tomato plants and each row has the same number of rhubarb plants. What is the greatest number of rows Li Na can plant?

Step-by-step explanation:

A method that you can use to find LCM is by just looking at the multiples of these numbers of the numbers an figure out which is the first similar one. You would say, well, let's see. The multiples of 18 are 18, 36, and I could keep going higher and higher, 54.And I could keep going. And the multiples of 12 are 12, 24, 36.And immediately I say, well, I don't have to go any further. I already found a multiple of both, and this is the smallest multiple of both. It is 36

9 rows

Step-by-step explanation:

Given that:

Li Na wants to plant 63 tomato plants and 81 rhubarb plants

However, Li Na was hoping with the mindset to plant the plants in rows;

where each row possesses the same number of tomato plants and rhubarb plants.

So;

Suppose we choose a given number, Let's say (9) to be the divisor for both the number of tomato plants and rhubarb plants;

Then

63/9 tomato plants = 7 tomato plants

81/9 rhubarb plants = 9 rhubarb plants

Therefore, the greatest number of rows Li Na can plant 7 tomato plants and 9 rhubarb  plants = 9
