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.
A, B, C = map(int, input().split())
for a in range(1,10**4+1):
    b = A/a
    c = C/a
    if b*c==B and int(b)==b and int(c)==c:
        #print(a,b,c)
        print(int(a*4 + b*4 + c*4))
        exit()
