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.
c=0
n=[int(n) for n in input().split()]
x1=(n[0]*n[1]//n[2])**(0.5)
x2=n[0]//x1
x3=n[1]//x1
print(int(4*(x1+x2+x3)))
