If we define proper factors as regular factors without one and the number itself, prime numbers do not have proper factors.
Proper factors are factors of the number except the number itself. So, with that said, the proper factors of 38 are 1, 2, and 19.
13 is a Prime number. It is only evenly divisible by itself and one.
The factors of 16 are: 1, 2, 4, 8, and 16.
The only prime factor of 16 is: 2.
The factors of 13 are 1 and 13. For them to be common, they need to be compared to another set of factors.
