Easily identify composites using multiplication
This will hopefully clear up some issues and save some time as well as disproving the goldston yildirim conjecture that 2,3,5 and 7 can be used to factor out all composites as primes create unique composites.
Out of curiousity what is the biggest composite number that you can come up with all prime factors? :). Can you hit a non prime every single time using a factor calculator? You can read more about my discovery at http://caculatecomposites.blogspot.com/ and yes this is mispelled, when i changed it they listed me about 65,343,231 down instead of 6 when doing a search. Composites are found gentlemen from the 2nd multiple of any whole number onward other than one. The reason being able to identify composites is so important is #1 you can simply list all the composites and the missing numbers will be prime or subtract them from #2 I challenge you using a factor calculator and traditional whole number (no decimal or one) to create any prime number. When you list multiple of a whole number, the multiple will always divide by the first or base multiple and thus cannot be prime (primes have one as a divisor) multiples of 7 all have 7 as divisors If youve been getting crashes doing searches for primes that is why. primes are factors calculated using whole numbers, never answers using traditional multiplication. The only way you can create a prime using a whole number is to multiply it by one and I dare you to defy this by simply trying it for yourself. hope this clears up some confusion and can any of you create a composite number with all prime factors? :)

Easily identify composites using multiplication
Can any of you easily create and spot a non prime number each time using any prime calculator or factor calculator?
would anyone mind using a factor calculator and try this formula 21+30=A then add 30 to each answer and test the result the result will be an even number ending in 1 that is not a prime or even number. Whats the largest composite found out of curiosity with all prime factors? Whats the largest composite that you can find with all prime factors?

Looks like a prime candidate for Miscalleneous Math Threads.

Anyone want to calculate the crank score for this one? I fear my PC lacks sufficient virtual memory to do the required multiprecision arithmetic.

Ironically, it may just one of the largest composites he's looking for. It's too early to tell which one the score may equal.

He has post count 0; very strange; is the server having virtual fever and halucinations?
Xyzzy, can you change his username to Nightmare360g ? H.
