C :

#include<stdio.h>

void main(){
	int i,n,s=0;
	scanf("%d",&n);
	
	for(i=1;i<=n;i++){
		if((i%2==0&&i%3==0)||(i%2==0&&i%5==0)||(i%2==0&&i%7==0)||(i%3==0&&i%5==0)||(i%3==0&&i%7==0)||(i%5==0&&i%7==0)||(i%2==0&&i%3==0&&i%5==0)||(i%2==0&&i%3==0&&i%7==0)||(i%3==0&&i%5==0&&i%7==0)||(i%2==0&&i%3==0&&i%5==0&&i%7==0)){
			s=s+i;
		}
	}
	printf("%d",s);
}

C++ :

#include <bits/stdc++.h>
using namespace std;

int main(){
	int n,i,c,s = 0;
	cin>>n;
	for(i = 1;i <= n;i++){
		c = 0;
		if(i % 2 == 0){
			c++;
		}
		
		if(i % 3 == 0){
			c++;
		}
		
		if(i % 5 == 0){
			c++;
		}
		
		if(i % 7 == 0){
			c++;
		}
		
		if(c >= 2){
			s = s + i;
		}
	}
	
	cout<<s<<endl;
}

Pascal :

var n,i,s:longint;
begin
read(n);
for i:=1 to n do
if (i mod 6=0)or(i mod 10=0)or(i mod 14=0)or(i mod 15=0)or(i mod 21=0)or(i mod 35=0) then s:=s+i;
write(s);
end.

Java :

import java.util.*;
public class Main{
	public static void main(String[] args){
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		int a = 0;
		for(int i = 1;i<=n;i++) {
			if ((i%2==0&&i%3==0)||(i%2==0&&i%5==0)||(i%2==0&&i%7==0)||(i%3==0&&i%5==0)||(i%3==0&&i%7==0)||(i%5==0&&i%7==0))
			{a += i ;
			}

		}
			System.out.println(a);
	}
}
//i%2==0&&i%3==0&&i%5==0&&i%7==0

Python :

n=int(input())
i=1
s=0
for i in range(1,n+1):
    if i%6==0 or i%10==0 or i%14==0 or i%15==0 or i%21==0 or i%35==0:
        s+=i
        i+=1
print(s)
