First, find the prime factorization. Use a factor tree.
189
63,3
21,3,3
7,3,3,3
All the other factors will be combinations of these. There are eight altogether.
You know that 1, 3 and 7 are factors. The rules of divisibility tells you that 9 is as well. Dividing them into 189 gives you the rest.
1, 3, 7, 9, 21, 27, 63, 189
