打表可以知道到后面增量都一样了,,
推论就是 i 和 i+1 互质
#include <cstdio> #include <algorithm> #include <cstring> #include <iostream> using namespace std; typedef long long ll; const ll mx = 120000; int main() { int cas = 0; ll x, k, y, dis, i; while (~scanf("%I64d%I64d", &x, &k)) { if (0 == x && 0 == k) break; for (i = 2; i <= k && i <= mx; ++i) { if (x % i == 0) continue; x = x / i * i + i; } if (i <= k) { dis = x / i * i + i - x; x += dis * (k - i + 1); } printf("Case #%d: %I64d\n", ++cas, x); } return 0; } /* 10000000 10000000 35670000000 150000 150001 65550437 */
