prime factor program in c code example

Example 1: prime number c program

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

Example 2: 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;
        
    }
