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: `101501` is 1 less than `101502` (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 `101501` is `10302453001`. Subtracting 1, we get `10302453000`. Note that `10302453000 ÷ 24 = 429268875`.
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: `101501 = 50751^2 - 50750^2 = 2575664001 - 2575562500`
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: `101501 = 110^2 + 299^2 = 12100 + 89401`, where `101501 = 4 × 25375 + 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: `101501` is of the form `4n+1`, where `n = 25375`.
