How to find the numbers divisible by 690?

Finding all the numbers that can be divided by 690 is essentially the same as searching for the multiples of 690: if a number N is a multiple of 690, then 690 is a divisor of N.

Indeed, if we assume that N is a multiple of 690, this means there exists an integer k such that:

$k \times 690 = N$

Conversely, the result of N divided by 690 is this same integer k (without any remainder):

$k = \frac{N}{690}$

From this we can see that, theoretically, there's an infinite quantity of multiples of 690 (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 690 less than 100000):

1 × 690 = 690
2 × 690 = 1380
3 × 690 = 2070
...
143 × 690 = 98670
144 × 690 = 99360
