standard outputVladik and Chloe decided to determine who of them is better at math. Vladik claimed that for any positive integer n he can represent fraction 
as a sum of three distinct positive fractions in form 
.
Help Vladik with that, i.e for a given n find three distinct positive integers x, y and z such that 
. Because Chloe can't check Vladik's answer if the numbers are large, he asks you to print numbers not exceeding 109.
If there is no such answer, print -1.
Input
The single line contains single integer n (1≤n≤104).
Output
If the answer exists, print 3 distinct numbers x, y and z (1≤x,y,z≤109, x≠y, x≠z, y≠z). Otherwise print -1.
If there are multiple answers, print any of them.
