How to find the numbers divisible by 689?

Finding all the numbers that can be divided by 689 is essentially the same as searching for the multiples of 689: if a number N is a multiple of 689, then 689 is a divisor of N.

Indeed, if we assume that N is a multiple of 689, this means there exists an integer k such that:

$k \times 689 = N$

Conversely, the result of N divided by 689 is this same integer k (without any remainder):

$k = \frac{N}{689}$

From this we can see that, theoretically, there's an infinite quantity of multiples of 689 (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 689 less than 100000):

1 × 689 = 689
2 × 689 = 1378
3 × 689 = 2067
...
144 × 689 = 99216
145 × 689 = 99905
