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 cmath import pi


a1, a2, a3 = map(int, input().split())

a = a1*a2*a3
a = int(a**0.5)

l1 = a//(a1)
l2 = a//(a2)
l3 = a//(a3)

print(4*(l1+l2+l3))
