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.
area = list(map(int,input().split()))
s1 = int(((area[0]*area[1]/area[2])**(1/2)))
s2 = int(((area[1]*area[2]/area[0])**(1/2)))
s3 = int(((area[2]*area[0]/area[1])**(1/2)))

print(4*(s1+s2+s3))
