How to find the numbers divisible by 2105?

Finding all the numbers that can be divided by 2105 is essentially the same as searching for the multiples of 2105: if a number N is a multiple of 2105, then 2105 is a divisor of N.

Indeed, if we assume that N is a multiple of 2105, this means there exists an integer k such that:

$k \times 2105 = N$

Conversely, the result of N divided by 2105 is this same integer k (without any remainder):

$k = \frac{N}{2105}$

From this we can see that, theoretically, there's an infinite quantity of multiples of 2105 (we can keep multiplying it by increasingly larger integers, without ever reaching the end).

However, in this instance, we've chosen to set an arbitrary limit (specifically, the multiples of 2105 less than 100000):

1 × 2105 = 2105
2 × 2105 = 4210
3 × 2105 = 6315
...
46 × 2105 = 96830
47 × 2105 = 98935
