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=[int(i) for i in input().split()]
ans=0
for i in range(1,area[0]+1):
    a=i
    c=area[0]/a
    b=area[1]/a
    if(b*c==area[2]):
        ans=(a+b+c)*4
        break
print(abs(ans))
