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.
area = list(map(int, input().strip().split()))
for i in range(area[0]+1):
    for j in range(area[1]+1):
        for k in range(area[2]+1):
            if i*j == area[0] and j*k == area[1] and k*i == area[2]:
                print((4*i)+(4*j)+(4*k))
