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.
a1, a2, a3 = map(int, input().split())

a = (a1 * a3 // a2) ** (0.5)
b = (a1 * a2 // a3) ** (0.5)
c = (a2 * a3 // a1) ** (0.5)

print(int(4 * (a + b + c)))
