Write a c program to show the prime factor of a given number.

/**
 * C program to find all prime factors of a given number
 */

#include <stdio.h>

int main()
{
    int i, j, num, isPrime;

    /* Input a number from user */
    printf("Enter any number to print Prime factors: ");
    scanf("%d", &num);

    printf("All Prime Factors of %d are: \n", num);

    /* Find all Prime factors */
    for(i=2; i<=num; i++)
    {
        /* Check 'i' for factor of num */
        if(num%i==0)
        {
            /* Check 'i' for Prime */
            isPrime = 1;
            for(j=2; j<=i/2; j++)
            {
                if(i%j==0)
                {
                    isPrime = 0;
                    break;
                }
            }

            /* If 'i' is Prime number and factor of num */
            if(isPrime==1)
            {
                printf("%d, ", i);
            }
        }
    }

    return 0;
}

prime number c program

int isPrime(int n) {
  for (int i = 2; i < n; i++) if (n % i == 0) return 0; 
  return 1;
}

prime factorization in c

#include <stdio.h>
#define MIN 100
#define MAX 100000


int main(){
    int pdiv=2,j;
    for (int num=MIN;num<=MAX;num++){
        printf("The prime factors of %d are:\n",num);
        j=num;
        do {
            
            if (j%pdiv==0)
            {
                
                printf("%d\n",pdiv);
                j=j/pdiv;
            }else
            {
               pdiv++; 
            }
            
            
        }while(j>1);
        pdiv=2;
        
    }
