Making a Factoring Program
11 Feb 2018 10:05:50 pm

I made a program that finds the factors of a program, but it begins to get very slow. Is there any way to make this program more efficient?

Code:




ClrHome


Input "Integer: ",A


1->Y


1->X


For(B,1,A\2


   If fPart(A/B)=0


   Then


      Y+1->Y


      If Y>10


      Then


         1->Y


         X+4->X


      End


      Output(Y,X,B


   End


End


Y+1->Y


If Y>10


Then


   1->Y


   X+4->X


End


Output(Y,X,A


Pause 


ClrHome

Also, how would I make this find negative factors?

For one, you could have it go from 1-int(root(B)+1). You could also test if Remainder is faster.
