C :

#include<stdio.h>

void main(){
    int i,n;
    scanf("%d",&n);

    for(i=1;i*i<=n;i++){
        if(n%i==0){
            printf("%d=%d*%d\n",n,i,n/i);
        }
    }
}

C++ :

#include <bits/stdc++.h>
using namespace std;
 
int main(){
    int n,j;
    cin>>n;
    for(int i = 1;i <= sqrt(n);i++){
    	if(n % i == 0){
    		cout<<n<<"="<<i<<"*"<<n/i<<endl;
		}
    }
}

Java :

import java.util.*;
public class Main{
	public static void main(String args[]){
		Scanner in = new Scanner(System.in);
		int n = in.nextInt();
		for(int i = 1;i<=n/2;i++){
			if(i<n/i&&n%i==0){
				System.out.println(n+"="+i+"*"+(n/i));
			}
		}
	}
}

Python :

import math
n=int(input())
i=1
while i <=math.sqrt(n):
    if n%i==0:
        print("%d=%d*%d"%(n,i,n//i))
    i=i+1
