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
line = list(map(int,input().split()))
ab = line[0]
bc = line[1]
ac = line[2]
a = math.sqrt((ab * ac) / bc)
b = math.sqrt((ab * bc) / ac)
c = math.sqrt((bc * ac) / ab)
print(3 * int(a + b + c))
