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,y,z = map(int,input().split())

t1 = (x*z)/y
t2 = (x*y)/z
t3 = (z*y)/x

t4 = t1**0.5
t5 = t2**0.5
t6 = t3**0.5

print(int(4*(t4 + t5+ t6)))
