Answer:
55 is not a Prime number. It is a composite number.
Definition:
A prime number has exactly two factors: 1 (also known as unity) and itself. A composite number has more than two factors; in other words, it has at least one factor besides 1 and itself.
Explanation:
Any number ending in 0 or 5 is evenly divisible by 5, so it has 5 as a factor. Thus, 55 is also divisible by 5, so it is a composite number.

Is 55 a composite or prime?
Composite 55 / 11 = 5
Is 55 composite or prime?
55 has factors other than 1 and itself, so it is not a prime number. For example, 55 is divisible by 5. (You can tell this because the last digit is a 5. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 55 is a composite number.composite

Examples of a composite number?
A composite number is a number which is not prime. All numbers are divided into the categories of either prime or composite (except for the number 1, which is neither). Examples of composite numbers are: 4,6,8,10 etc. All even numbers and square numbers are composite. There are, however, odd and non-square numbers that are composite as well, such as 15,21,27 and 55.
