The factors of any prime-like number (for this definition a number not divisible by 2 or 3) can be found by dividing it by 6 +-1 and placing it on its' specific matrix.

Are these tables useful in creating a pattern out of primes or is this just another sieve that I've made?

I'm a non-maths guy but I've really had fun playing with primes for the last few weeks so I don't mind if all I do is keep creating sieves, you never know I might get there eventually...

Take any number that is not divisible by 2 or 3 call it X

(for this example a number < 1000 if you want to find it on the matrices above)

(X-1)/6=A (Only if A is a whole number otherwise discard it)

(X+1)/6=B (Only if B is a whole number otherwise discard it)

(Every number not divisible by 2 or 3 will either be an A or a B)

If you have an A find it on table A1 or A2.

When you have found A get a C value from the top…

If you found your A on table A1 multiply your C by 6 and add 1,

This is one of the factors of X.

If you found your A on table A2 multiply your C by 6 and subtract 1

This is one of the factors of X.

If you did not find your A on A1 or A2 it is a prime number.

If you have a B find it on table B multiply your C by 6 and subtract 1 this is a factor of X.

If you did not find your B on table B it is a prime number.

(I derived the matrices from 6BC+B+C=A and 2 variations thereof)
