I'm not sure this project does anything useful, but I created a team anyway. From their boards - "factordb is a repository for integer factorizations that are used in many areas: aliquot sequences, homeprime sequences, the Cunningham project, odd perfect number research, and many others. By factoring numbers in the database, all of these areas benefit. You'd have to look up the individual projects that use factordb for more info."
