C-Program to Print GCD and LCM

#include<stdio.h>

int main()

{

int num1,num2,temp1,temp2,gcd,lcm,x;

printf("Enter number 1\n");

scanf("%d",&num1);

printf("Enter number 2\n");

scanf("%d",&num2); 

temp1=num1;

temp2=num2;

while(temp2!=0)

{

x=temp2;

temp2=temp1%temp2;

temp1=x;

}

gcd=temp1;

lcm=(num1*num2)/gcd;

printf("gcd is %d\n",gcd);

printf("Lcm is %d\n",lcm);

return 0; 

}
