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: `57601` is 1 more than `57600` (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 `57601` is `3317875201`. Subtracting 1, we get `3317875200`. Note that `3317875200 ÷ 24 = 138244800`.
3) Difference of squares: Every prime number greater than 2 can be expressed as the difference of the squares of two consecutive natural numbers.
Example: `57601 = 28801^2 - 28800^2 = 829497601 - 829440000`
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: `57601 = 1^2 + 240^2 = 1 + 57600`, where `57601 = 4 × 14400 + 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: `57601` is of the form `4n+1`, where `n = 14400`.
