This calculator performs the decomposition of a number into its prime factors and lists all its natural divisors. Enter an integer between 1 and 1,000,000.
1) Relation to multiples of 6: Every prime number greater than 3 is always one less or one more than a multiple of 6.
Example: `2549` is 1 less than `2550` (multiple of 6).
2) Square minus 1 divisible by 24: For every prime number greater than 3, if 1 is subtracted from its square, the result is always divisible by 24.
Example: The square of `2549` is `6497401`. Subtracting 1, we get `6497400`. Note that `6497400 ÷ 24 = 270725`.
3) Difference of squares: Every prime number greater than 2 can be expressed as the difference of the squares of two positive integers.
Example: `2549 = 1275^2 - 1274^2 = 1625625 - 1623076`
4) Sum of two squares: Every prime number of the form `4n+1` (where n is a positive natural number) can be expressed as the sum of two squares.
Example: `2549 = 7^2 + 50^2 = 49 + 2500`, where `2549 = 4 × 637 + 1`.
5) Form `4n+1` or `4n-1`: Except for the number 2, all prime numbers follow the pattern `4n+1` or `4n-1`, where `n` is a natural number.
Example: `2549` is of the form `4n+1`, where `n = 637`.
