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.
x = list(map(int, input().split()))

a = x[0] * x[1] / x[2]
a = a**0.5

b = x[1] * x[2] / x[0]
b = b**0.5

c = x[2] * x[0] / x[1]
c = c**0.5

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