Hello, Thanks for your feedback and the pointer to PARI/GP. About existing stuff, it seems there is none written in Java: I asked the question on stackoverflow a while ago, nobody knows any library for the JVM. About the applications, well, I agree it is not the #1 required functionality in most applications. Still applications beyond pure maths do exist: hash tables, pseudo random numbers, cryptography, electronics... Clearly the int range is not enough for the standard public key cryptography however it is enough for most of other applications (and standard crypto stuff is fairly covered out of the box by java anyway).
I propose this because I looked for it, and ended up spending significant time coding and testing it, so I though it would be useful to include it in a library such as commons.math.

There are quite a few open source libraries providing integer factorization, e.g. pari/gp (http://pari.math.u-bordeaux.fr/). The question is, why do you think such a functionality would be useful for commons math? There aren't all that much practical use cases for factorization, in particular if it is limited to the Java integer range, unless you want to implement a computer algebra system or you have to deal with certain specific problems in discrete mathematics (neither of which is in the focus of commons math).
