To find the factors of a number, you first need to split that number into its prime factors. In the case of 15, this produces:
15 = 3x5
The next step is to note that every factor of the number (apart from 1) is the product of any combination of its prime factors. Thus, the factors of 15 are:
1, 3, 5 and 15.

How many factors do you have to list when it asks you find all of the whole number factors?
All of them. Different numbers have different numbers of factors.
How many whole numbers less than 10 have an odd numbers of unique factors?
A whole number has an odd number of unique factors if and only if it is a perfect square. The perfect squares less than 10 are 0, 1, 4, and 9. Therefore, there are four whole numbers less than 10 that have an odd number of unique factors.

Is There A Limit To How Many factor a whole number greater than 0 can have?
The limit is infinity if the factors do not have to be whole numbers. If you stipulate that the factors have to be whole numbers, then, yes, for each number, there is a limit to how many factors it has. For example, the number 4 has only 3 whole-number factors: 1, 2, and 4.
