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: `103237` is 1 more than `103236` (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 `103237` is `10657878169`. Subtracting 1, we get `10657878168`. Note that `10657878168 ÷ 24 = 444078257`.
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: `103237 = 51619^2 - 51618^2 = 2664521161 - 2664417924`
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: `103237 = 14^2 + 321^2 = 196 + 103041`, where `103237 = 4 × 25809 + 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: `103237` is of the form `4n+1`, where `n = 25809`.
