How to find the numbers divisible by 87?
Finding all the numbers that can be divided by 87 is essentially the same as searching for the multiples of 87: if a number N is a multiple of 87, then 87 is a divisor of N.
Indeed, if we assume that N is a multiple of 87, this means there exists an integer k such that:
Conversely, the result of N divided by 87 is this same integer k (without any remainder):
From this we can see that, theoretically, there's an infinite quantity of multiples of 87 (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 87 less than 100000):
- 1 × 87 = 87
- 2 × 87 = 174
- 3 × 87 = 261
- ...
- 1148 × 87 = 99876
- 1149 × 87 = 99963
