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.
def main():
	import math
	#x= A x B	y= B x C 	z= C x A
	x,y,z= [int(i) for i in input().split()]
	p=x*y*z
	print(round(4*(math.sqrt(p//(x*x))+ math.sqrt(p//(y*y))+ math.sqrt(p//(z*z)))))
	return 0

	main()
