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 *
temp=input()
temp=temp.split(" ")
ab=int(temp[0])
bc=int(temp[1])
ca=int(temp[2])

a=sqrt((ab*ca)/bc)
c=ca/a
b=bc/c
sum=int(4*(a+b+c))
print(sum)
