No, 8 is an even number. ALL prime numbers are odd numbers (excluding 2), that does not mean, however, that all odd numbers are prime numbers. Prime numbers do not have any divisors, even numbers do. Let's say the this number is 18. We know 1 and 18 are one set of divisors. But there are more: 2 and 9, and 3 and 6, thus concluding it is not a Prime number. Short list of prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53... and by now you should have noticed the pattern--all numbers that end in 1, 3, 7, 9 are prime.

Is 88 a composite number or prime number?
88 is a composite number because it is an even number. All numbers greater than 8 and less than 100 are composites if they are even numbers, if they are multiples of 3 or 7, or if they end in 5 or 0.
Is 124 a prime number or a composite number?
Answer:124 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, 2, 4, 6, or 8 is evenly divisible by 2, so it has 2 as a factor. 124 is also divisible by 2, so it is a composite number.
Common factors of 8 and 14?
Common factors of two or more given numbers are expressed as prime numbers that all given numbers can be divided by and still result in a whole number. The smallest prime number is 2. Since the largest of the two numbers (14) divided by 2 is 7, the primes that exist beginning with 2 and ending with 7 are: 2, 5 and 7 Since 8 is not divisible into a whole number by either 5 or 7, the only common factor for both 8 and 14 is 2.
A number is chosen at random from the first 20 positive whole numbers What is the probability that it is not a prime number?
There are 12 composite (and 8 primes) in the first twenty whole numbers. So the probability of randomly choosing a non-prime is 12/20 or 60%.
What is the prime number between 8 and 13?
The prime number between 8 and 13 is 11.
Why can't a whole number ending with 8 be a prime?
The only even prime number is 2.

No. It is even and so divisible by 2.
Why cant a whole number ending in 8 be prime?
Whole numbers ending in 8 are even numbers. All even numbers except for 2 are composite numbers.
Can a whole number ending in 8 be prime?
No. It's an even number, i.e. divisible by 2.
Can a whole number ending in eat be prime?
A number ending in 8 cannot be prime because 8 is an even number. Any even number can be divided evenly by 2 as well as itself and 1, and a prime number is a number that cannot be divided evenly by any number except itself and 1.
Can a hole number ending in 8 be prime?
No.
Can a number ending in 8 be prime?
No, it can't. If a number ends in 8, it is divisible by 2, itself, and 1, so it is not prime.
What is a number ending in 8 that is the product of 2 consecutive whole numbers?
There is no such number.
Why isn't 8 nor 9 a prime number?
If it is divisible by a whole number that isn't 1 and gets another whole number, it is not prime. 8 is divisible by both 2 and 4. 9 is divisible by 3.
Is 88 a prime a composite number?
Composite. All positive, whole numbers greater than two and ending in 0, 2, 4, 6 or 8 are composite.
Is the number 68 prime or composite?
Composite. All positive, whole numbers greater than two and ending in 0, 2, 4, 6 or 8 are composite.
Is the number 24 composite or prime?
Composite. All positive, whole numbers greater than two and ending in 0, 2, 4, 6 or 8 are composite.
