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.
g = input().split()
d = []
for i in range(3):
    d.append(int(g[i]))
s1, s2, s3 = d[0], d[1], d[2]
a = (s2 * s3 / s1) ** (1 / 2)
b = (s1 * s3 / s2)** (1 / 2)
c = (s1 * s2 / s3) ** (1 / 2)
print(int(4 * (a + b + c)))
