We study in detail the asymptotic behavior of the number of ordered factori
zations with a given number of factors. Asymptotic formulae are derived for
almost all possible values of interest. In particular. the distribution of
the number of factors is asymptotically normal. Also we improve the error
term in Kalmar's problem of "factorisatio numerorum" and investigate the av
erage number of district factors in a random ordered factorization. (C) 200
