The code is appropriately given below with comments for better understanding

Explanation:

#include <linux/init.h>

#include <linux/module.h>

#include <linux/kernel.h>

#include <linux/hash.h>

#include <linux/gcd.h>

#include <asm/param.h>

#include <linux/jiffies.h>

/* This function is called when the module is loaded. */

static int simple_init(void)

{

  printk(KERN_INFO "Loading Module\n");

  printk(KERN_INFO "These are the HZ: %d\n", HZ);

  printk(KERN_INFO "These are the jiffies: %lu\n", jiffies);

  printk(KERN_INFO "Golden Ratio is: %lu\n", GOLDEN_RATIO_PRIME);  

  return 0;

}

/* This function is called when the module is removed. */

static void simple_exit(void) {

  printk(KERN_INFO "Removing Module");

  unsigned long a = gcd(3300, 24);

  printk(KERN_INFO "Greatest Common Denominator between 3,300 and 24 is: %lu\n", a);

  printk(KERN_INFO "These are the jiffies: %lu\n", jiffies);

}

/* Macros for registering module entry and exit points. */

module_init( simple_init );

module_exit( simple_exit );
