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: `47017` is 1 more than `47016` (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 `47017` is `2210598289`. Subtracting 1, we get `2210598288`. Note that `2210598288 ÷ 24 = 92108262`.
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: `47017 = 23509^2 - 23508^2 = 552673081 - 552626064`
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: `47017 = 19^2 + 216^2 = 361 + 46656`, where `47017 = 4 × 11754 + 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: `47017` is of the form `4n+1`, where `n = 11754`.
