## C Program to Find all Prime Factors of the Number and Print it on Command Line

## Source Code

```
/**
* 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;
}
