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())
s = []
for i in range(1,min(a,b)+1):
    if(a%i==0 and b%i==0):
        s.append(i)
# print(s)
ans = []
for i in s:
    if(((a//i)*(b//i))==c):
        ans.append(i)
        ans.append(b//i)
        ans.append(a//i)
print(sum(ans)*4)
