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.
#the areas are s1,s2 and s3
#a ,b and c be lemgth of sides that have common vertex
import math
s1,s2,s3=map(int,input().split())
a=math.sqrt((s1*s3)/s2)
#print(a)
b=math.sqrt((s1*s2)/s3)
#print(b)
c=math.sqrt((s2*s3)/s1)
#print(c)
print("%d"%(4*(a+b+c)))
