1. Using iterative Approach

#include<stdio.h>

int main(){

int num;

printf("Enter any number:");

scanf("%d",&num);

for(int i=1;i<num;i++){

if(num%i==0) printf("%d ",i);

else if(i>num/2){

printf("%d ",num);

break;

}

}

}

2. Using Recurssive Approach

#include<stdio.h>

void factors(int num, int div){

if(num%div==0)

printf("%d ",div);

if(div<=num/2)

factors(num, div+1);

else printf("%d ",num);

}

int main(){

int num;

printf("Enter any number:");

scanf("%d",&num);

factors(num,1);

}
