Default Game coding

Hi, Iam new to this forum so please bear with me.

I am currently studying how coding in a game work since I want to be a game developer someday and right now I am studying how in-game items are turned into codes like gold and stuff... I ve already isolated the packet and confirmed that every increase and decrease in it's value is multiplied by 64.... for example I increase the value by 60 the code i have is increase by 3840 but I am stumped on how they arrived at the code... my value is 16773 but the code I have is 1087398208... please explain how they vot this code. Thanks in advance.
