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

# a_1 =  a1*a2
# a_2 =  a2*a3
# a_3 =  a1*a3

 
if __name__ == '__main__' :
    a_1, a_2, a_3 = [int(i) for i in input().split()]
    a1 = math.sqrt((a_1*a_3)/a_2)
    a2 = math.sqrt((a_2*a_1)/a_3)
    a3 = math.sqrt((a_3*a_2)/a_1)
    print(4*sum([a1, a2, a3]))
