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: `56501` is 1 less than `56502` (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 `56501` is `3192363001`. Subtracting 1, we get `3192363000`. Note that `3192363000 ÷ 24 = 133015125`.
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: `56501 = 28251^2 - 28250^2 = 798119001 - 798062500`
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: `56501 = 130^2 + 199^2 = 16900 + 39601`, where `56501 = 4 × 14125 + 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: `56501` is of the form `4n+1`, where `n = 14125`.
