How to find the numbers divisible by 781?

Finding all the numbers that can be divided by 781 is essentially the same as searching for the multiples of 781: if a number N is a multiple of 781, then 781 is a divisor of N.

Indeed, if we assume that N is a multiple of 781, this means there exists an integer k such that:

$k \times 781 = N$

Conversely, the result of N divided by 781 is this same integer k (without any remainder):

$k = \frac{N}{781}$

From this we can see that, theoretically, there's an infinite quantity of multiples of 781 (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 781 less than 100000):

1 × 781 = 781
2 × 781 = 1562
3 × 781 = 2343
...
127 × 781 = 99187
128 × 781 = 99968
