Is 45005 a prime or composite number?
"Composite" means that the number has smaller factors; "prime" means that it doesn't. Look at the last digit. If the digit is 0, 2, 4, 6, or 8, the number is divisible by 2. If the last digit is 0 or 5, the number is divisible by 5. If it none of those, the number may still have additional factors; but checking for this last digit can often quickly give you an answer.

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
Is 360 a prime or composite number?
A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 360 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 5. (You can tell this because the last digit is a 0. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 360 is a composite number.
Is the number 2005 a composite number?
