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.
x = input().split()
p=int(x[0])
q=int(x[1])
r=int(x[2])

a =((p*r)//q)**0.5
b=((p*q)//r)**0.5
c=((r*q)//p)**0.5
print(int(4*(a+b+c)))
