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.
row = input().split()

area1 = int(row[0])
area2 = int(row[1])
area3 = int(row[2])

import math
len1 = int(math.sqrt(area1*area3/area2))
len2 = int(math.sqrt(area1*area2/area3))
len3 = int(math.sqrt(area2*area3/area1))



print (int((len1*4) + (len2*4) + (len3*4)))
