想法：这道题要找质因子，所以首先把2到100000左右的质数全找出来，利用素数筛法。经过分析可知，一个数n的质因子要么全小于根号下n，或存在一个大于根号下n的因子，因此可以缩小搜索范围。#include#include#include#include#include#include#include#include#includeusingnamespacestd;intprime[100005];

题目大意：输入一个正整数，要求输出该正整数的素数分解因素，并按照要求格式输出；分析：首先用素数筛选法找出一定范围内的所有素数，然后按照从小到达的顺序，对该正整数进行素数分解；那么筛选素数的范围到底要多大呢？该题中正整数N的范围是longint(-2147483648～2147483647),素数只要筛选到100000即可，因为1000002>2147483647，如果分解后的部分不能被100000
