6 and 9 are not prime numbers 23 is the only prime number in this group
next prime number would be 11
23 is a prime number but 9 and 22 can both be factored 9 is 3x3 and 22 is 2x11
The prime factorization of 9 is 3 x 3 or 3^23*3
A prime number is only divisible evenly by 1 and itself, so yes a prime number has to be divided by a prime number (the number being itself). A prime number is any number that is only divisible by one and itself. So the prime number 11 is prime because only 1 and itself (11) can divide it. 11 is prime because it is not divisible by 2, 3, 4, 5, 6, 7, 8, 9, or 10. If 11 was divisible by a prime number, like 3 then it would no longer be prime. These are all the prime numbers up to 100: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 81, 89, and 97.

23 is a prime number but 9 and 22 can both be factored 9 is 3x3 and 22 is 2x11
No - because neither 4 nor 9 is a prime number. The product of these numbers is 3960 - the prime factorization of which is as follows: 23 x 32 x 5 x 11
5, 11 and 17 are prime number but 9 and 27 are composite numbers
9 is not a prime number as it is divisible by 3
23 is a prime number - it will not divide by 3, 9 or 6 !
9. They are: 2, 3, 5, 7, 11, 13, 17, 19, and 23.
Since 23 is a prime number, the highest number that will be able to divide evenly into both itself and 9 is the number 1.
