题目描述
You are given an integer $n$ .
You can perform any of the following operations with this number an arbitrary (possibly, zero) number of times:
1. Replace $n$ with $\frac{n}{2}$ if $n$ is divisible by $2$ ;
2. Replace $n$ with $\frac{2n}{3}$ if $n$ is divisible by $3$ ;
3. Replace $n$ with $\frac{4n}{5}$ if $n$ is divisible by $5$ .
For example, you can replace $30$ with $15$ using the first operation, with $20$ using the second operation or with $24$ using the third operation.
Your task is to find the minimum number of moves required to obtain $1$ from $n$ or say that it is impossible to do it.
You have to answer $q$ independent queries.

You have to answer $q$ independent queries.
输入格式
The first line of the input contains one integer $q$ ( $1 \le q \le 1000$ ) — the number of queries.
The next $q$ lines contain the queries. For each query you are given the integer number $n$ ( $1 \le n \le 10^{18}$ ).
The next $q$ lines contain the queries. For each query you are given the integer number $n$ ( $1 \le n \le 10^{18}$ ).
输出格式
Print the answer for each query on a new line. If it is impossible to obtain $1$ from $n$ , print -1. Otherwise, print the minimum number of moves required to do it.
