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.
import math
f1, f2, f3 = map(int, input(). strip(). split())
cute = f1*f2*f3
c = math.sqrt(cute)/f1
b = math.sqrt(cute)/f3
a = math.sqrt(cute)/f2
print((int(a)+int(b)+int(c))*4)
