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 = tuple([int(item) for item in input().split()])
a = ((area1*area2*area3)**0.5)/area1
b = ((area1*area2*area3)**0.5)/area2
c = ((area1*area2*area3)**0.5)/area3
print(int(4*(a+b+c)))
