Problem Statement

You are given an integer N.

Find a triple of positive integers h, n and w such that 4/N = 1/h + 1/n + 1/w.

If there are multiple solutions, any of them will be accepted.

Constraints

It is guaranteed that, for the given integer N, there exists a solution such that h,n,w \leq 3500.

Inputs

Input is given from Standard Input in the following format:

N

Outputs

Print a triple of positive integers h, n and w that satisfies the condition, in the following format:

h n w

Sample Input 1

2

Sample Output 1

1 2 2

4/2 = 1/1 + 1/2 + 1/2.

Sample Input 2

3485

Sample Output 2

872 1012974 1539173474040

It is allowed to use an integer exceeding 3500 in a solution.

Sample Input 3

4664

Sample Output 3

3498 3498 3498

Solution in Python (3.4.3) (judge verdict: Accepted)

N=int(input())
a=4/N
h_st=max(int(N*(1/4))-1,1)
#h_st=1
for h in range(h_st,3501):
    H=1/h
    for n in range(1,3501):
        a=(4*h*n-N*n-N*h)
        #print(h,n)
        if a:
            w=N*h*n/a
            if w>0 and w.is_integer():
                print(h,n,int(w))
                exit()

print(h,n,w)
