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
arr = input().split(' ')
s1 = int(arr[0])
s2 = int(arr[1])
s3 = int(arr[2])
a = sqrt((s1*s2)/s3)
b = sqrt((s1*s3)/s2)
c = sqrt((s3*s2)/s1)
print(4*(int(a)+int(b)+int(c)))
