# Software to determine relationship between natural numbers

I am looking for something that could, given a set of natural numbers, find the possible relations between them.

For example, given {2,3,5}, return "All relatively prime; First prime numbers".

Though data mining software might be used for this, I believe it has to be trained to do this, and I would like to avoid this.

The Operating System is not a concern to me.

• For which operating system? Are you willing to pay for it?

• @unor I am not concerned about the OS. Regarding payment, we'll see about that. Jun 18 '16 at 8:38
• The On-Line Encyclopedia of Integer Sequences (OEIS) could (partially?) solve your problem. For more details and usage examples look here. Jun 21 '16 at 20:43
• Is that really possible by analyzing the data? Why are { 2, 3, 5 } not the first 3 items of the formula y = 0.5x²+0,5x+2 (at x=0, 1, 2)? Jun 21 '16 at 20:48
• Give me n numbers and I'll find a polynomial through all those numbers. Jun 21 '16 at 20:49
