Darius bakes 18 muffins for his friends, he gives each of his friends an equal number has none left over. How could he divided the muffins

So he made 18 muffins for each of his friends and he has none left

so it can be divided by:

2 friends ... 18/2 = 9 ... each getting 9 muffins

3 friends ... 18/3 = 6 ... each getting 6 muffins

6 friends ... 18/6 = 3 ... each getting 3 muffins

9 friends ... 18/9 = 2 ... each getting 2 muffins

18 friends ... 18/1 = 18 ... each getting 1 muffin
