The museum's show for July features 30 oil paintings by different artists. All artists show the same number of paintings and each artist shows more than 1 painting. How many artists could be featured in the show?
Five of them if they each have six paintings or 6 of them if they have 5 paintings
The other answerer is right, you can also have 2 each with 15 artists - 30 divided by 2 is 15.
