**Problem Description**

**Input**

Input will consist of multiple problem instances. The first line of the input will contain a single integer indicating the number of problem instances. Each instance will consist of a single line of the form m n1 n2 n3 ... nm where m is the number of integers in the set and n1 ... nm are the integers. All integers will be positive and lie within the range of a 32-bit integer.

**Output**

For each problem instance, output a single line containing the corresponding LCM. All results will lie in the range of a 32-bit integer.

**Sample Input**

2 3 5 7 15 6 4 10296 936 1287 792 1
