How to find the numbers divisible by 861?

Finding all the numbers that can be divided by 861 is essentially the same as searching for the multiples of 861: if a number N is a multiple of 861, then 861 is a divisor of N.

Indeed, if we assume that N is a multiple of 861, this means there exists an integer k such that:

$k \times 861 = N$

Conversely, the result of N divided by 861 is this same integer k (without any remainder):

$k = \frac{N}{861}$

From this we can see that, theoretically, there's an infinite quantity of multiples of 861 (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 861 less than 100000):

1 × 861 = 861
2 × 861 = 1722
3 × 861 = 2583
...
115 × 861 = 99015
116 × 861 = 99876
