So, if I understand this correctly (which I'm sure I don't), this makes me wonder if we can do this the other way? ie, Can we multiply y mod x by a prime from P with a 93 digit exponent, and...

I thought of that several hours later when I realized that x had 141 factors, so it makes sense that it can solve the problem with 142 primes from P. I ran your...

It gives me an answer where each prime that gets an exponent > 0, gets an exponent that is between 91-94 digits long. One strange thing I'm seeing is that whether I use...

Yes, x has only small prime factors p^e, with p a prime < 1000 and where e is usually 1, but can be higher, like 2^13, or 3^8, 7^5, etc. Also, all p are less than the smallest prime in P, ie no...

Is there a way to test if a particular prime, p_i, from P could never be part of a solution? Either alone or in a group? Like, test whether p_i^e_i == y (mod x) ever/never has a solution, or if...
 Forum: Factoring 2021-06-25, 20:24 Replies: 17 Views: 816 Posted By WraithX How to find a number with factors only from a set of primes? Does anyone know of a way to find, or construct, a number B = k*x + y with x and y given, that is only divisible by primes from a finite set of primes P? For example, if x=97929 and y=83261 and P...
