题目:输入两个正整数m和n,求其最大公约数和最小公倍数。
//程序分析:利用辗除法。
#include<stdio.h>
int main(){
int a,b,num1,num2,temp;
printf("please input two number:\n");
scanf("%d%d",&num1,&num2);
if(num1<num2){
temp = num1;
num1 = num2;
num2 = temp;
}
a = num1;
b = num2;
while(b!=0){ /*利用辗除法,直到b为0为止*/
temp = a%b;
a=b;
b=temp;
}
printf("gongyueshu:%d\n",a);
printf("gongbeishu:%d\n",num1*num2/a);
}
