How to find the numbers divisible by 10000?

Finding all the numbers that can be divided by 10000 is essentially the same as searching for the multiples of 10000: if a number N is a multiple of 10000, then 10000 is a divisor of N.

Indeed, if we assume that N is a multiple of 10000, this means there exists an integer k such that:

$k \times 10000 = N$

Conversely, the result of N divided by 10000 is this same integer k (without any remainder):

$k = \frac{N}{10000}$

From this we can see that, theoretically, there's an infinite quantity of multiples of 10000 (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 10000 less than 100000):

1 × 10000 = 10000
2 × 10000 = 20000
3 × 10000 = 30000
...
9 × 10000 = 90000
10 × 10000 = 100000
