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.
a1, a2, a3 = [int(i) for i in input().split()]

# como a1 = x*y a2 = x*z a3 = y*z areas dos retangulos temos que a1*a2/a3 = x*x portanto x = raiz disso

x = ((a1*a2)/a3)**0.5
y = ((a1*a3)/a2)**0.5
z = ((a2*a3)/a1)**0.5

soma = (4*x) + (4*y) + (4*z)
print(soma)
