I have not come across this function before (and I am a number theorist!). I am guessing on what it means: applied to a set of integers (?) or positive integers, it checks whether the gcd of any two is also in the set? One problem I see is that you would want it to be a global function, rather than a member function of some class (which class?), which is rather a negative for a specialised function. I hope you do not mind me calling it that since I have never needed such a function in around 40 years of number-theoretic computations!
