It is still called a polynomial.
If an expression does not have a common factor, then it is called a "prime" expression.
The number 6 can be factored into 2 x 3. So 6 cubed can be factored into 2 cubed times 3 cubed. In either case, the result is equal to 216.
It is 23 and 1 because 23 is a prime number
257 is a prime and can only be factored by 1 and itself, but any number can be divided by any number.
If a number cannot be factored it is a prime number.
It is called a composite number
composite
All composite numbers can be expressed as unique products of prime numbers. This is known as a prime factorization.
because one number is being factored by the other number. and the numbers in a multiplication problem are just called factors anyway. hope this helped you.

-5 Is Not A Valid Number.
No. It can be factored as 13*47.
Yes.
Every nonzero whole number can be factored.
composite
When a number can only be factored by 1 and itself or cannot be factored at all it is considered prime.
