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: `90017` is 1 less than `90018` (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 `90017` is `8103060289`. Subtracting 1, we get `8103060288`. Note that `8103060288 ÷ 24 = 337627512`.
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: `90017 = 45009^2 - 45008^2 = 2025810081 - 2025720064`
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: `90017 = 49^2 + 296^2 = 2401 + 87616`, where `90017 = 4 × 22504 + 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: `90017` is of the form `4n+1`, where `n = 22504`.
