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())
periphary = 4 * (((a1*a2/a3)**(1/2)) + ((a1*a3/a2)**(1/2)) + ((a3*a2/a1)**(1/2)))  
print(periphary)
