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.
list1=input().split(" ")
list1=[int(a) for a in list1]
x=((list1[0]*list1[1])/list1[2])**0.5
y=((list1[1]*list1[2])/list1[0])**0.5
z=((list1[2]*list1[0])/list1[1])**0.5
print(int(4*(x+y+z)))
