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: `95189` is 1 less than `95190` (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 `95189` is `9060945721`. Subtracting 1, we get `9060945720`. Note that `9060945720 ÷ 24 = 377539405`.
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: `95189 = 47595^2 - 47594^2 = 2265284025 - 2265188836`
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: `95189 = 158^2 + 265^2 = 24964 + 70225`, where `95189 = 4 × 23797 + 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: `95189` is of the form `4n+1`, where `n = 23797`.
