Question

Write a c program to find out the gcd and lcm of two numbers

Answer 1

Answer: C program to find HCF and LCM: The code below find the highest common factor and the least common multiple of two integers. HCF is also known as the greatest common divisor (GCD) or the greatest common factor (GCF)

#include <stdio.h>

 

int main() {

 int a, b, x, y, t, gcd, lcm;

 

 printf("Enter two integers\n");

 scanf("%d%d", &x, &y);

 

 a = x;

 b = y;

 

 while (b != 0) {

   t = b;

   b = a % b;

   a = t;

 }

 

 gcd = a;

 lcm = (x*y)/gcd;

 

 printf("Greatest common divisor of %d and %d = %d\n", x, y, gcd);

 printf("Least common multiple of %d and %d = %d\n", x, y, lcm);

 

 return 0;

}
