    for n in range(2, number):
        if number % n == 0:
            return n
        if n == number - 1 and number - 1 % n != 0:
            return 0
def Fmmax():
    for n in range(number-1, 1, -1):
        if number % n == 0:
            return n
        if n == 2 and number % n != 0:
            return 0
