I want to plant 45 sunflower plants, 81 corn plants and 63 tomato plants in my garden. If I put the same number of plants in each row and each row has only one type of plant, what is the greatest number of plants I can put in one row?

Question

Here is what I think
Factors of 45: 1, 3, 5, 9, 15, 45 81: 1, 3, 9, 27, 81 63: 1, 3, 7, 9, 21, 63

I can put 9 in each row

Is the answer 9 or not?
