C語言練習(xí)題

從鍵盤輸入兩個(gè)數(shù)m和n，求其最大公約數(shù)和最小公倍數(shù)。

實(shí)現(xiàn)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(yùn)行結(jié)果為：
