In general, it is not possible. Composite and primes can be infinitely large and finding possible factors or proving that there are none is not always possible.
neither prime or composite
It is prime
It would be impossible to list them all, since numbers go on forever, but here are some of them: 2 - Prime 3 - Prime 4 - Composite 5 - Prime 6 - Composite 7 - Prime 8 - Composite 9 - Composite 10 - Composite 11 - Prime 12 - Composite 13 - Prime 14 - Composite 15 - Composite 16 - Composite 17 - Prime 18 - Composite 19 - Prime 20 - Composite 21 - Composite 22 - Composite 23 - Prime 24 - Composite 25 - Composite 26 - Composite 27 - Composite 28 - Composite 29 - Prime 30 - Composite 31 - Prime 32 - Composite 33 - Composite 34 - Composite 35 - Composite 36 - Composite 37 - Prime 38 - Composite 39 - Composite 40 - Composite 41 - Prime 42 - Composite 43 - Prime 44 - Composite 45 - Composite 46 - Composite 47 - Prime 48 - Composite 49 - Composite 50 - Composite
To write a BASIC program that checks if an input number is prime or composite, you can use a loop to test divisibility. First, prompt the user for a number and then check if it's less than 2 (which is neither prime nor composite). For numbers greater than 1, iterate from 2 to the square root of the number, checking if it divides evenly (using the modulus operator). If you find a divisor, the number is composite; otherwise, it's prime. Here's a simple example: INPUT "Enter a number: ", N IF N < 2 THEN PRINT "Neither prime nor composite": END IS_PRIME = TRUE FOR I = 2 TO SQR(N) IF N MOD I = 0 THEN IS_PRIME = FALSE EXIT FOR END IF NEXT I IF IS_PRIME THEN PRINT N; " is prime" ELSE PRINT N; " is composite"

Use Wolfram|Alpha... go to the related link below, Wolfram|Alpha, and type in (is __ (number) prime) and then the program will compute that and tell you if it is prime or composite.

One is not prime and not composite.
