21, 55, 77, and 93 are composite numbers. 23 is a prime.
The composite factors of 1485 are 9, 15, 27, 33, 45, 55, 99, 135, 165, 297, 495, 1485
composite because it has more than two factors
It ends with a 5 and so is evenly divisible by 5.
Prime numbers are numbers that can only be multiplied itself and one.For ex.87 is a prime number. You can't multiply a number to get 87. Composite is a number that can be multiplied by other numbers than itself. For ex.55 is a commposite number. 11 and 5 can get you 55. Hope u understand! Good luck!
27 and 55 are composite numbers but 13 is a prime number
55 is a composite number because it has other factors aside from 1 and itself. The other factors of 55 are 5 and 11.

yes it is. - turtles rock man :-)
It has more than two factors.
Anything that isn't 1, 5, 11, 55

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.
Composite 55 / 11 = 5
composite because it has more than two factors
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
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.
