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 main():
    s1, s2, s3 = [int(i) for i in input().split()]
    a = (s3 * s1 / s2) ** 0.5
    b = s1 / a
    c = s2 / b
    print(int((a + b + c) * 4))
