While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

As programmer, your job is to create solutions.
Here we help you fix your code, but your code show no attempt to solve the problem.

To know how many numbers are divisor of a given number, the brute force solution (simple but inefficient) is to check every single possible divisor.
To know if a number is divisor, the most simple solution is to check if division have a reminder or not.
