输入包含多个问题的实例。输入的第一行包含一个整数问题实例的数量。每个实例都包含一个单一的形式M N1 N2 N3线…nm M集与N1的整数…nm的整数。所有的整数是正躺在一个32位整数范围。

每个问题的实例，输出一行包含相应的LCM。所有的结果都会躺在一个32位的整数范围。-Enter the instance contains multiple issues. The first line of input contains an integer number of problem instances. Each instance consists of a single line in the form of M N1 N2 N3 ... integer nm M set and N1, ... nm integer. All integers are lying a 32-bit integer range. Each instance of the problem, the output line contains the corresponding LCM. All results will be lying in a range of 32-bit integers.
