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: `2909` is 1 less than `2910` (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 `2909` is `8462281`. Subtracting 1, we get `8462280`. Note that `8462280 ÷ 24 = 352595`.
3) Difference of squares: Every prime number greater than 2 can be expressed as the difference of the squares of two positive integers.
Example: `2909 = 1455^2 - 1454^2 = 2117025 - 2114116`
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: `2909 = 10^2 + 53^2 = 100 + 2809`, where `2909 = 4 × 727 + 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: `2909` is of the form `4n+1`, where `n = 727`.
