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.
A,B,C = list(map(int, input().split()))

for i in range((A*B)+1):
    for j in range((A*B)+1):
        if i*j == A:
            k = B/j
            if k*i == C:
                print(4*(int(i)+int(j)+int(k)))
