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.
def sol(a):
    ans = a+1
    for i in range(2, int(a**0.5)+1):
        if not(a%i):
            ans = (a//i) + i
            break
    return 2*ans

l = list(map(int, input().split()))
res = 0

for i in l:
    res += sol(i)

print(res)
