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())

common = []
for i in range(2, max(a, b, c) + 1):
    if a % i == 0 and b % i == 0 and c % i == 0:
        common.append(i)


if a == b == c:
    print(a * 12)
elif a != b != c:
    print(*common)
else:
    fact = common[0]
    print(fact * 8 + c // fact * 4)
