30 is composite number as it can be expressed as 1 x 2 x 3 x 5 i.e in terms of other prime numbers.

1 is not a prime, and is uninformative as a factor. It is a divisor of both prime and composite numbers.

A prime number is a number that cannot be factored by 2 other whole numbers.

30 is a composite number because all even numbers (with the exclusion of 2) are composite.
