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: `32353` is 1 more than `32352` (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 `32353` is `1046716609`. Subtracting 1, we get `1046716608`. Note that `1046716608 ÷ 24 = 43613192`.
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: `32353 = 16177^2 - 16176^2 = 261695329 - 261662976`
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: `32353 = 32^2 + 177^2 = 1024 + 31329`, where `32353 = 4 × 8088 + 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: `32353` is of the form `4n+1`, where `n = 8088`.
