Hello Devs,

In this tutorial, we are going to learn C program to calculate Prime factor of a number

Here is a well-commented example you can understand and analyze.

#include < stdio.h >
int main(){
int num,i=1,j,k;
printf("\nEnter a number:");
scanf("%d",&num);
while(i<=num){
k=0;
if(num%i==0){
 j=1;
  while(j<=i){
	if(i%j==0)
		 k++;
	 j++;
  }
  if(k==2)
	 printf("\n%d is a prime factor",i);
}
i++;
}
return 0;
}


I hope this example helps you.
