    I have a problem

    English:

    Say how many diferent numbers can be formed as the result of the product of one, two, or more of the next numbers: 5, 22, 91, 455, 2002, 199945, 877758, 438790, 48266900.
    For example: 5 (5), 2002 (22*91), 45374875 (5*455*19945), etc.

    Spanish:

    Decir cuántos números distintos se pueden formar como resultado del producto de uno, dos, o
    más de los siguientes números, sin repetir: 5, 22, 91, 455, 2002, 19945, 87758, 438790,
    48266900.
    Por ejemplo: 5 (5), 2002 (22·91), 45374875 (5·455·19945), etc.

    I think i solved it in python

    Python pastebin - collaborative debugging tool

    How many different numbers(possible products)? Isn't it just ΣC(i,9) from i=1 to i=9? ...or something like that, I've forgotten too much of those math classes.
