find hcf and lcm C program

The code below finds highest common factor and least common multiple of two integers. HCF is also known as greatest common divisor(GCD) or greatest common factor(gcf).

#include <stdio.h>
 #include <conio.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;
}
