C語言練習題

從鍵盤輸入兩個數m和n，求其最大公約數和最小公倍數。

實現方法如下：

main()
{
    int m,n,a,b;
    int p,r,temp;
    printf("Please input 2 integer(m,n):");
    scanf("%d,%d",&m,&n);
    a = m; b = n;
    if(b<a)
    {
        temp = a;
        a = b;
        b = temp;
    }
    p = a * b;
    while(a != 0)
    {
        r = b % a;
        b = a;
        a = r;
    }

    printf("The Greatest Common Divisor %d and %d is: %d/n",m,n,b);
    printf("The Least Common Multiple %d and %d is: %d/n",m,n,p/b);
}

運行結果為：
