解题思路:

注意事项:

参考代码:

#include<stdio.h>

int least_num(int a,int b)

{

    return a%b==0 ? b : least_num(b, a % b);

}

int great_num(int a, int b)

{

    return a * b / least_num(a, b);

}

int main()

{

    int a, b, c,d;

    scanf("%d %d %d", &a, &b, &c);

    d = great_num(a, b);

    d = great_num(d, c);

    printf("%d", d);

    return 0;

}
