It is composed of four distinct prime numbers multiplied together. it has a total of sixteen divisors. So we are looking for 16 divisors of a large number and we need something like this 7 × 181 × 508 but that is only an example of three distinct prime numbers, we need 4 that multiple into a large number in the thousands. From my understanding, that is my perspective above. I don't want anyone to solve this for me, but leading me in the right direction or giving me an equation would help.

I'm not sure what you are doing but here is a nudge in the right direction ... 508 is not a prime number.

I know, I was stating that I need prime numbers to solve for the solution. Do you have any idea how I'd solve this? Or what type of math it is?

so there is no possible way to solve it?

There is a large database of integer sequences maintained for precisely this reason. Your sequence can be found here. 1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120 - OEIS The usefulness is that once you get several candidates for the next few integers or even better, a closed form, you can try to understand the sequence in the context of its origin for your problem. Often sequences can be understood in many different contexts and Richard Stanley famously included a section of exercises in his book which derived the Catalan numbers as the solution to over 50 seemingly distinct problems.

Alright, thanks! Would this problem coincide with "nearly impossible" ?
