题目描述
You are given several queries. Each query consists of three integers p , q and b . You need to answer whether the result of p/q in notation with base b is a finite fraction.
A fraction in notation with base b is finite if it contains finite number of numerals after the decimal point. It is also possible that a fraction has zero numerals after the decimal point.
输入格式
The first line contains a single integer n ( 1≤n≤105 ) — the number of queries.
Next n lines contain queries, one per line. Each line contains three integers p , q , and b ( 0≤p≤1018 , 1≤q≤1018 , 2≤b≤1018 ). All numbers are given in notation with base 10 .
输出格式
For each question, in a separate line, print Finite if the fraction is finite and Infinite otherwise.
