Question

Lucy has 80 bean plants, 64 tomato plants, and 16 pepper plants. She wants to put the plants in rows with only one type of plant in each row. All rows will have the same number of plants.

Answer 1

Find the greatest common factor(the highest number that is a factor of all three amounts of plants):
GCF = 8
There will be 8 plants in each row.

Bonus: How many rows will there be? First, divide each amount plants by the number of plants per row:


80 divide 8 = 10

64 divide 8 = 8

16 divide 8 = 2

Then add the quotients:

10+ 8+ 2 = 20

There will be 20 rows of plants: 10 of beans, 8 of tomatoes, and 2 of peppers.
