How many prime factorization does 120 have?
Every positive composite number only has one unique prime factorization.
How many composite numbers are between 1 and 99?
Look up a list of prime numbers (a Google search for "prime numbers" or "list of prime numbers" should do); every number (greater than 1) that is NOT a prime number is composite.
How many even prime numbers in between 1 and 150?
Oh, what a happy little question! Well, there is only one even prime number, and that's number 2. Even though most prime numbers are odd, 2 is a special one because it's the only even prime number. Just like every color has its place on the canvas, every number has its unique role in mathematics.
Is every odd number is prime or not?
No, there are many odd numbers that are not prime: 9, 15, 21, 25, 27, etc. However, 2 is the only even number that is prime, since all other even numbers are divisible by 2.
How many whole number factor of 54?
There are 8. Also, by definition factors must be whole numbers because otherwise every non-zero number is a factor of every number (including prime numbers).
