7.4 穷举法编程计算两个整数的最小公倍数

#include <stdio.h>#include <stdlib.h>int main(){    int a,b,num1,num2,c;    printf("输入a b:");    scanf("%d%d",&num1,&num2);    if(num1>num2)    {        c=num1;        num1=num2;        num2=c;    }    a=num1;    b=num2;    while(b!=0)    {        c=a%b;        a=b;        b=c;    }    printf("最小公倍数是: %d\n",num1*num2/a);    return 0;}
