Write a Program to find the GCD and LCM of two integer numbers

#include<stdio.h>
#include<conio.h>
main()
{
    int m,n,temp,lcm,gcd;
    clrscr();
    printf("Enter the two numbers\n");
    scanf("%d%d",&m,&n);
    temp=m*n;
    while(m!=n)
    {
    if(m>n)
      m=m-n;
      else
      n=n-m;
    }
    gcd=n;
    lcm=temp/gcd;
    printf("LCM =%d\t GCD =%d",lcm,gcd);
    getch();
    return;
}
