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.
from math import sqrt
area1, area2, area3 = [int(s) for s in input().split()]
print(int(4*sqrt((area1*area3)/area2)+4*sqrt((area1*area2)/area3)+4*sqrt((area2*area3)/area1)))
