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: `86441` is 1 less than `86442` (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 `86441` is `7472046481`. Subtracting 1, we get `7472046480`. Note that `7472046480 ÷ 24 = 311335270`.
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: `86441 = 43221^2 - 43220^2 = 1868054841 - 1867968400`
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: `86441 = 104^2 + 275^2 = 10816 + 75625`, where `86441 = 4 × 21610 + 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: `86441` is of the form `4n+1`, where `n = 21610`.
