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: `52369` is 1 more than `52368` (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 `52369` is `2742512161`. Subtracting 1, we get `2742512160`. Note that `2742512160 ÷ 24 = 114271340`.
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: `52369 = 26185^2 - 26184^2 = 685654225 - 685601856`
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: `52369 = 63^2 + 220^2 = 3969 + 48400`, where `52369 = 4 × 13092 + 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: `52369` is of the form `4n+1`, where `n = 13092`.
