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.
from math import sqrt

# faces
x, y, z = map(int, input().split())

# edges a, b, c
# x = a * b
# y = b * c
# z = a * c

# a = x/b = z/c
# b = x/a = y/c
# c = y/b = z/a

# a^2 = x * z / y
# b^2 = x * y / z
# c^2 = y * z / x

# soma = a*4 + b*4 + c*4

a = sqrt(x * z / y)
b = sqrt(x * y / z)
c = sqrt(y * z / x)

print(int(4*(a+b+c)))
