You've got a rectangular parallelepiped with integer edge lengths. You know the areas of its three faces that have a common vertex. Your task is to find the sum of lengths of all 12 edges of this parallelepiped.
The first and the single line contains three space-separated integers — the areas of the parallelepiped's faces. The area's values are positive ( &gt; 0) and do not exceed 10<sup class="upper-index">4</sup>. It is guaranteed that there exists at least one parallelepiped that satisfies the problem statement.

def answer(d, e, f):
    a = int(math.sqrt((d * e) // f))
    b = d // a
    c = e // a
    return (a + b + c) * 4
    
def main():
    d, e, f = [int(i) for i in sys.stdin.readline().split()]
    print(answer(d, e, f))
    return
