最大公约数及最小公倍数

#include <stdio.h>
main()
{
int a,b,c,m,t;
printf("Please input two numbers;\n");
scanf("%d%d",&a,&b);
if(a<b)
{
t = a;
a = b;
b = t;
}
m = a * b;
c = a % b;
while(c != 0)
{
a = b;
b = c;
c = a % b;
}
printf("The max commen divisor:\n%d\n",b);  //输出最大公约数
printf("The min commen multiple:\n%d\n",m/b);  //输出最小公倍数
return 0;
