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: `73553` is 1 less than `73554` (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 `73553` is `5410043809`. Subtracting 1, we get `5410043808`. Note that `5410043808 ÷ 24 = 225418492`.
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: `73553 = 36777^2 - 36776^2 = 1352547729 - 1352474176`
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: `73553 = 112^2 + 247^2 = 12544 + 61009`, where `73553 = 4 × 18388 + 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: `73553` is of the form `4n+1`, where `n = 18388`.
