    Let n be the number we want ...
    Let x and y be its largest factors ....

    we know,
    xy=n ...
    (pedantically xy = nk where k is some integer but it that would mean i can find a factor greater than x or y)

    and x+y = 340

    y=n/x
    so x+n/x = 340

    ok now try to proceed from here ...

    Note: there are, of course, an infinite number of correct solutions.
