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
a1,a2,a3=map(int,input().split())
#a1=ab a2=bc a3=ca => c=a3/a, a=a1/b,a3/c  c=a2/b   b = a1/a,a2/c =>
# c=a3/a1/b => a3*a2/c*a1 => c = (a2*a3/a1)**0.5
# Similarly a^2 = a1*a3/a2, b^2 = a1*a2/a3


sm = 4*( ((a2*a3)//a1)**0.5 + ((a1*a3)//a2)**0.5 + ((a1*a2)//a3)**0.5 )
print(int(sm))
