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: `38113` is 1 more than `38112` (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 `38113` is `1452600769`. Subtracting 1, we get `1452600768`. Note that `1452600768 ÷ 24 = 60525032`.
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: `38113 = 19057^2 - 19056^2 = 363169249 - 363131136`
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: `38113 = 68^2 + 183^2 = 4624 + 33489`, where `38113 = 4 × 9528 + 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: `38113` is of the form `4n+1`, where `n = 9528`.
