How to find the numbers divisible by 221?
Finding all the numbers that can be divided by 221 is essentially the same as searching for the multiples of 221: if a number N is a multiple of 221, then 221 is a divisor of N.
Indeed, if we assume that N is a multiple of 221, this means there exists an integer k such that:
Conversely, the result of N divided by 221 is this same integer k (without any remainder):
From this we can see that, theoretically, there's an infinite quantity of multiples of 221 (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 221 less than 100000):
- 1 × 221 = 221
- 2 × 221 = 442
- 3 × 221 = 663
- ...
- 451 × 221 = 99671
- 452 × 221 = 99892
