题意描述
Limak is an old brown bear. He often plays poker with his friends. Today they went to a casino. There are n players (including Limak himself) and right now all of them have bids on the table. i-th of them has bid with size a i dollars.
Each player can double his bid any number of times and triple his bid any number of times. The casino has a great jackpot for making all bids equal. Is it possible that Limak and his friends will win a jackpot?
给你几个数字,你可以对这些数字进行无限次的乘2和乘3操作,询问你最后是否能将它们变为相同
思路
假设最后相同的数字为k,则得到式子:2x3xz=k,我们只需要将每个数所有的2和3去除,最后判断数字是否相同即可
