查找 HCF 和 LCM 的 C 程序： 下面的代码查找两个整数的最大公因数和最小公倍数。 HCF 也称为最大公约数 (GCD) 或最大公因数 (GCF)。

C 中两个数的 HCF

#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;
}

使用递归查找hcf和lcm的C程序

#include <stdio.h>


long gcd(long, long);

int main() {
  long x, y, hcf, lcm;

  printf("Enter two integers\n");
  scanf("%ld%ld", &x, &y);

  hcf = gcd(x, y);
  lcm = (x*y)/hcf;

  printf("Greatest common divisor of %ld and %ld = %ld\n", x, y, hcf);
  printf("Least common multiple of %ld and %ld = %ld\n", x, y, lcm);

  return 0;
}

long gcd(long a, long b) {
  if (b == 0)
    return a;
  else
    return gcd(b, a % b);
}

使用函数查找hcf和lcm的C程序

#include <stdio.h>


long gcd(long, long);

int main() {
  long x, y, hcf, lcm;

  printf("Enter two integers\n");
  scanf("%ld%ld", &x, &y);

  hcf = gcd(x, y);
  lcm = (x*y)/hcf;

  printf("Greatest common divisor of %ld and %ld = %ld\n", x, y, hcf);
  printf("Least common multiple of %ld and %ld = %ld\n", x, y, lcm);

  return 0;
}

long gcd(long x, long y) {
  if (x == 0) {
    return y;
  }

  while (y != 0) {
    if (x > y)
      x = x - y;
    else
      y = y - x;
  }

  return x;
}
