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
inputs = [int(num) for num in input().split()]
a1=inputs[0]
a2=inputs[1]
a3=inputs[2]
pro =int(math.sqrt(a1*a2*a3))
a=pro//a1
b=pro//a2
c=pro//a3
print((a+b+c)*4)
