How to compute the divisors of 2726?

A number N is said to be divisible by a number M (with M non-zero) if, when we divide N by M, the remainder of the division is zero.

$N mod M = 0$

Brute force algorithm

We could start by using a brute-force method which would involve dividing 2726 by each of the numbers from 1 to 2726 to determine which ones have a remainder equal to 0.

$Remainder = N - (M \times ⌊ \frac{N}{M} ⌋)$

(where $⌊ \frac{N}{M} ⌋$ is the integer part of the quotient)

2726 / 1 = 2726 (the remainder is 0, so 1 is a divisor of 2726)
2726 / 2 = 1363 (the remainder is 0, so 2 is a divisor of 2726)
2726 / 3 = 908.66666666667 (the remainder is 2, so 3 is not a divisor of 2726)
...
2726 / 2725 = 1.0003669724771 (the remainder is 1, so 2725 is not a divisor of 2726)
2726 / 2726 = 1 (the remainder is 0, so 2726 is a divisor of 2726)

Improved algorithm using square-root

However, there is another slightly better approach that reduces the number of iterations by testing only integers less than or equal to the square root of 2726 (i.e. 52.211109928826). Indeed, if a number N has a divisor D greater than its square root, then there is necessarily a smaller divisor d such that:

$D \times d = N$

(thus, if $\frac{N}{D} = d$ , then $\frac{N}{d} = D$ )

2726 / 1 = 2726 (the remainder is 0, so 1 and 2726 are divisors of 2726)
2726 / 2 = 1363 (the remainder is 0, so 2 and 1363 are divisors of 2726)
2726 / 3 = 908.66666666667 (the remainder is 2, so 3 is not a divisor of 2726)
...
2726 / 51 = 53.450980392157 (the remainder is 23, so 51 is not a divisor of 2726)
2726 / 52 = 52.423076923077 (the remainder is 22, so 52 is not a divisor of 2726)
