How to find the numbers divisible by 855?

Finding all the numbers that can be divided by 855 is essentially the same as searching for the multiples of 855: if a number N is a multiple of 855, then 855 is a divisor of N.

Indeed, if we assume that N is a multiple of 855, this means there exists an integer k such that:

$k \times 855 = N$

Conversely, the result of N divided by 855 is this same integer k (without any remainder):

$k = \frac{N}{855}$

From this we can see that, theoretically, there's an infinite quantity of multiples of 855 (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 855 less than 100000):

1 × 855 = 855
2 × 855 = 1710
3 × 855 = 2565
...
115 × 855 = 98325
116 × 855 = 99180
