How to find the numbers divisible by 80?

Finding all the numbers that can be divided by 80 is essentially the same as searching for the multiples of 80: if a number N is a multiple of 80, then 80 is a divisor of N.

Indeed, if we assume that N is a multiple of 80, this means there exists an integer k such that:

k × 80 = N

Conversely, the result of N divided by 80 is this same integer k (without any remainder):

k = N 80

From this we can see that, theoretically, there's an infinite quantity of multiples of 80 (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 80 less than 100000):

  • 1 × 80 = 80
  • 2 × 80 = 160
  • 3 × 80 = 240
  • ...
  • 1249 × 80 = 99920
  • 1250 × 80 = 100000
