* C Program to find HCF of a given Number without using Recursion
int hcf(int, int);
int a, b, result;
printf("Enter the two numbers to find their HCF: ");
scanf("%d%d", &a, &b);
result = hcf(a, b);
printf("The HCF of %d and %d is %d.\n", a, b, result);
int hcf(int a, int b)
while (a != b)
if (a > b)
a = a - b;
b = b - a;
$ cc pgm31.c $ a.out Enter the two numbers to find their HCF: 24 36 The HCF of 24 and 36 is 12.
