* C Program to Find LCM of a Number using Recursion
int lcm(int, int);
int a, b, result;
printf("Enter two numbers: ");
scanf("%d%d", &a, &b);
result = lcm(a, b);
printf("The LCM of %d and %d is %d\n", a, b, result);
int lcm(int a, int b)
static int common = 1;
if (common % a == 0 && common % b == 0)
$ cc pgm22.c $ a.out Enter two numbers: 456 12 The LCM of 456 and 12 is 456 $ a.out Enter two numbers: 45 75 The LCM of 45 and 75 is 225
