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: `54497` is 1 less than `54498` (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 `54497` is `2969923009`. Subtracting 1, we get `2969923008`. Note that `2969923008 ÷ 24 = 123746792`.
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: `54497 = 27249^2 - 27248^2 = 742508001 - 742453504`
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: `54497 = 104^2 + 209^2 = 10816 + 43681`, where `54497 = 4 × 13624 + 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: `54497` is of the form `4n+1`, where `n = 13624`.
