题目1439:Least Common Multiple WA解决

题目描述:
The least common multiple (LCM) of a set of positive integers is the smallest positive integer which is divisible by all the numbers in the set. For example, the LCM of 5, 7 and 15 is 105.
输入:
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.
输出:
For each problem instance, output a single line containing the corresponding LCM. All results will lie in the range of a 32-bit integer.
样例输入:
2
3 5 7 15
6 4 10296 936 1287 792 1
样例输出:
105
10296

思路:
WA半天,做到怀疑人生,最终花了我20个豆子解决,题目要求lie in the range of 32-bit integer.int是到2^32-1。int不够,要longlong才行。真的一个-1没看清,浪费了好多时间。
