What are the numbers divisible by 4005?

How to find the numbers divisible by 4005?

Finding all the numbers that can be divided by 4005 is essentially the same as searching for the multiples of 4005: if a number N is a multiple of 4005, then 4005 is a divisor of N.

Indeed, if we assume that N is a multiple of 4005, this means there exists an integer k such that:

$k\times 4005=N$

Conversely, the result of N divided by 4005 is this same integer k (without any remainder):

$k=\frac{N}{\mathrm{4005}}$

From this we can see that, theoretically, there's an infinite quantity of multiples of 4005 (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 4005 less than 100000):

• 1 × 4005 = 4005
• 2 × 4005 = 8010
• 3 × 4005 = 12015
• ...
• 23 × 4005 = 92115
• 24 × 4005 = 96120
