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.
area1, area2, area3 = [int(i) for i in input().split()]
side1 = ((area1*area3)//area2)**(1/2)
side2 = ((area3*area2)//area1)**(1/2)
side3 = ((area1*area2)//area3)**(1/2)
ans = int(4 * (side1 + side2 + side3))
print(ans)
