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.
arr = list(map(int,input().split()))
for i in arr:
    a = i**0.5
    if a == int(a):
        break
a = int(a)
b = (sum(arr)-(a**2))//(2*a)
print((8*a)+(b*4))
