The purpose of this paper is not to solve a problem but to pose one that may be of some interest, depth, and consequence.Given that the positive integer n has the canonical representation n = Πh i=1 pi αi the problem of finding the number F(n) = f(α1, α2, ... αn) of ordered factorizations of n into positive nontrivial integral factors is equivalent to that of finding the number of ordered partitions of the vector (α1, α2, ... αn) into nonzero vectors with nonnegative integral components.
