C语言输入两个正整数m和n,求其最大公约数和最小公倍数
#include "stdio.h" #include "conio.h" main() { int a,b,num1,num2,temp; printf("please input two numbers:\n"); scanf("%d,%d",&num1,&num2); if(num1<num2)/*交换两个数,使大数放在num1上*/ { 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); getch(); }
