C :

#include<stdio.h>
int main()
{
	int j;
	for(j=100000000;j>=0;j--)
	{
		if(j%105==0)
		{
			printf("%d",j);
			break;
		}
	}
	return 0;
} 

C++ :

#include <iostream>
using namespace std;
int main()
{
	int i;
	for(i=100000000;i>0;i--)
	{
		if(i%3==0&&i%5==0&&i%7==0)
		{
			cout<<i;
			break;
		}
	}
	return 0;
}

Pascal :

var
  max,i,j:longint;

begin
  max:=0;
  for i:=1 to 20000000 do
  begin
  j:=i*5;
  if (j mod 3=0) and  (j mod 7=0) then
    if j>max then max:=j;
    end;
    writeln(max);

end.

Java :

public class Main {
	public static void main(String[] args) {
		System.out.println(99999900);
	}
}
