How to find the numbers divisible by 550?

Finding all the numbers that can be divided by 550 is essentially the same as searching for the multiples of 550: if a number N is a multiple of 550, then 550 is a divisor of N.

Indeed, if we assume that N is a multiple of 550, this means there exists an integer k such that:

$k \times 550 = N$

Conversely, the result of N divided by 550 is this same integer k (without any remainder):

$k = \frac{N}{550}$

From this we can see that, theoretically, there's an infinite quantity of multiples of 550 (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 550 less than 100000):

1 × 550 = 550
2 × 550 = 1100
3 × 550 = 1650
...
180 × 550 = 99000
181 × 550 = 99550
