How to find the numbers divisible by 645?
Finding all the numbers that can be divided by 645 is essentially the same as searching for the multiples of 645: if a number N is a multiple of 645, then 645 is a divisor of N.
Indeed, if we assume that N is a multiple of 645, this means there exists an integer k such that:
Conversely, the result of N divided by 645 is this same integer k (without any remainder):
From this we can see that, theoretically, there's an infinite quantity of multiples of 645 (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 645 less than 100000):
- 1 × 645 = 645
- 2 × 645 = 1290
- 3 × 645 = 1935
- ...
- 154 × 645 = 99330
- 155 × 645 = 99975
