                                  各位的题解都这么复杂？ 最简题解（目前）：

                                  #include <stdio.h>
int main() {
    int n;
    scanf("%d", &n);
    bool a = false;

    if (n % 3 == 0) {
        printf("%d ", 3);
        a = true;
    }

    if (n % 5 == 0) {
        printf("%d ", 5);
        a = true;
    }

    if (n % 7 == 0) {
        printf("%d ", 7);
        a = true;
    }

    if (!a)
        printf("n");

}

                                  其中的a用于判断是否无法被任何数输出。
