How to find the numbers divisible by 8000?

Finding all the numbers that can be divided by 8000 is essentially the same as searching for the multiples of 8000: if a number N is a multiple of 8000, then 8000 is a divisor of N.

Indeed, if we assume that N is a multiple of 8000, this means there exists an integer k such that:

$k \times 8000 = N$

Conversely, the result of N divided by 8000 is this same integer k (without any remainder):

$k = \frac{N}{8000}$

From this we can see that, theoretically, there's an infinite quantity of multiples of 8000 (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 8000 less than 100000):

1 × 8000 = 8000
2 × 8000 = 16000
3 × 8000 = 24000
...
11 × 8000 = 88000
12 × 8000 = 96000
