Facebook account associated with my number?

[ccccc]

Okay so I've let friends use my phone to go onto the Facebook app to check notifications etc, but now my number is associated with their Facebook accounts for example, my mum downloaded an app and searched for friends to play it with from email/Facebook and my name came up like 10 times with all different email addresses but they were all my friends that I'd let sign into Facebook on my phone, can anyone tell me how to remove this so my number isn't associated with anyone else's Facebook account
