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
iarr = list(map(int,input().split()))
a1 = iarr[0]
a2 = iarr[1]
a3 = iarr[2]
pro = a1*a2*a3
c = int(sqrt(pro//(a1*a1)))
a = int(sqrt(pro//(a2*a2)))
b = int(sqrt(pro//(a3*a3)))
print(4*(a+b+c))
