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: `49369` is 1 more than `49368` (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 `49369` is `2437298161`. Subtracting 1, we get `2437298160`. Note that `2437298160 ÷ 24 = 101554090`.
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: `49369 = 24685^2 - 24684^2 = 609349225 - 609299856`
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: `49369 = 120^2 + 187^2 = 14400 + 34969`, where `49369 = 4 × 12342 + 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: `49369` is of the form `4n+1`, where `n = 12342`.
