Explain your answer. If her reasoning is incorrect, explain how she should have found the answer.
The factors of 10 are incorrect. They should be 1, 2, 5, and 10. The factors of 24 are also incorrect. 5 would not be a factor of 24. The common factors of 10, 24, and 40 are 1 and 2 so she could only put 1 or 2 movies on each shelf.
