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.
import math
a1,a2,a3=map(int,input().split()) #a1,a2,a3=ab,bc,ca. find (a+b+c)*4
a=math.ceil(math.sqrt(a1*a3//a2))
b=a1//a
c=a2//b
s=(a+b+c)*4
print(s)
