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.
num=list(map(int,input().split()))
a=1
print(num)
for i in range(3):
    a=a*num[i]
len=lambda x:a/x
l=list(map(len,num))
print(int(4*sum((l))))
