    Generating function problem

    Hi, can anyone help me with this:

    Using generating functions, find in how many ways can you get the number 25 by adding the numbers 1, 2, 5 and 10.

    $\large{\left( {\sum\limits_{k = 0}^{25} {{x^k}} } \right)\left( {\sum\limits_{k = 0}^{13} {{x^{2k}}} } \right)\left( {\sum\limits_{k = 0}^5 {{x^{5k}}} } \right)\left( {\sum\limits_{k = 0}^3 {{x^{10k}}} } \right)}$
