    n! = 7! * 5! * 3!

    n! = 7! * (5 * 4 * 3 * 2 * 1) * (3 * 2 * 1)

    n! = 7! * (2 * 4 * 3 * 3 * 2 * 5)

    n! = 7! * (8 * 9 * 10)

    n! = 10!

    it is just what it says it is.

    If you want the long term,

    n! = 7.6.5.4.3.2.1.5.4.3.2.1.3.2.1

    (where . indicates multiplication)

    n! = 7! * 5! * 3!

    n! = 5040 * 120 * 6

    n! = 3628800

    n = 10
