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: `33797` is 1 less than `33798` (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 `33797` is `1142237209`. Subtracting 1, we get `1142237208`. Note that `1142237208 ÷ 24 = 47593217`.
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: `33797 = 16899^2 - 16898^2 = 285576201 - 285542404`
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: `33797 = 79^2 + 166^2 = 6241 + 27556`, where `33797 = 4 × 8449 + 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: `33797` is of the form `4n+1`, where `n = 8449`.
