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,b,c = map(float,input().split())
s1 = int(((a*b)/c)**.5)
s2 = int(((a*c)/b)**.5)
s3 = int(((b*c)/a)**.5)
print(4*(s1+s2+s3))
