2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder.

What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?

```
using System;
public class Program
{
public static void Main()
{
int i = 1;
int mod = 1;
do
{
mod = 0;
for (int j = 1; j <= 20; j++)
{
mod += i % j;
if (mod != 0)
{
i++;
break;
}
}
} while (mod != 0);
Console.WriteLine(i);
}
}
```
