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.
a=[int(i) for i in input().split()]
vol=int(pow(a[0]*a[1]*a[2],0.5))
l=vol//a[0]
b=vol//a[1]
h=vol//a[2]
print(4*(l+b+h))
