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 = [int(i) for i in input().split()]

def find_common(a, b, c):
    for i in range(max(1, min(min(a, b), 2)), min(a, b)+1):
        if a%i==0 and b%i==0:
            if c%(b//i)==0:
                return i
    return  1      
comm = find_common(a, b, c)

c, d, e = comm, a//comm, b//comm

print((c+d+e)*4)
