How to find the numbers divisible by 280?
Finding all the numbers that can be divided by 280 is essentially the same as searching for the multiples of 280: if a number N is a multiple of 280, then 280 is a divisor of N.
Indeed, if we assume that N is a multiple of 280, this means there exists an integer k such that:
Conversely, the result of N divided by 280 is this same integer k (without any remainder):
From this we can see that, theoretically, there's an infinite quantity of multiples of 280 (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 280 less than 100000):
- 1 × 280 = 280
- 2 × 280 = 560
- 3 × 280 = 840
- ...
- 356 × 280 = 99680
- 357 × 280 = 99960
