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: `55717` is 1 more than `55716` (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 `55717` is `3104384089`. Subtracting 1, we get `3104384088`. Note that `3104384088 ÷ 24 = 129349337`.
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: `55717 = 27859^2 - 27858^2 = 776123881 - 776068164`
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: `55717 = 31^2 + 234^2 = 961 + 54756`, where `55717 = 4 × 13929 + 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: `55717` is of the form `4n+1`, where `n = 13929`.
