How to find the numbers divisible by 686?

Finding all the numbers that can be divided by 686 is essentially the same as searching for the multiples of 686: if a number N is a multiple of 686, then 686 is a divisor of N.

Indeed, if we assume that N is a multiple of 686, this means there exists an integer k such that:

$k \times 686 = N$

Conversely, the result of N divided by 686 is this same integer k (without any remainder):

$k = \frac{N}{686}$

From this we can see that, theoretically, there's an infinite quantity of multiples of 686 (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 686 less than 100000):

1 × 686 = 686
2 × 686 = 1372
3 × 686 = 2058
...
144 × 686 = 98784
145 × 686 = 99470
