How to find the numbers divisible by 691?

Finding all the numbers that can be divided by 691 is essentially the same as searching for the multiples of 691: if a number N is a multiple of 691, then 691 is a divisor of N.

Indeed, if we assume that N is a multiple of 691, this means there exists an integer k such that:

$k \times 691 = N$

Conversely, the result of N divided by 691 is this same integer k (without any remainder):

$k = \frac{N}{691}$

From this we can see that, theoretically, there's an infinite quantity of multiples of 691 (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 691 less than 100000):

1 × 691 = 691
2 × 691 = 1382
3 × 691 = 2073
...
143 × 691 = 98813
144 × 691 = 99504
