When I try to add my phone number to my iCloud account it does not allow me to and says "This phone number is already in use with another account". I do not recall linking my phone number with any other account. Is there a way to remove my number from the unknown account it is linked up with so that I may add my number to my actual account?

To enter an Apple ID account you must have the questions and answers written with you , once you enter the account by filling up the details go to accounts and click on edit .
Scroll down in the window and to remove an old mobile number click on cross sign , to add a new mobile number click on add more and check the small circle of phone number and fill up the details - click on continue and finally save it .
This method applies for both old apple id account and new account , condition you need Apple ID questions and answers to enter it .
Whoever is the owner of the another account will reset it see this article If you forgot your Apple ID password - Apple Support
Or if I he / she knows the question and answers for Apple ID that person can enter the apple id account , then he can delete your mobile number from the account .
You can't enter his account without his permissions ( and if luckily he reveals the data to you ) , then this problem can be solved .

I do exactly as you say but it does not allow me to add my number because my number is apparently being used for another account that is not mine. That is the problem I am trying to resolve.
Cannot verify phone number
