Is 37 and 42 prime or composite?
37 is prime, 42 is composite.
Do you need to know all the factors of a number to decide if its prime or composite?
No. If the number has one factor (other than 1 and itself) it is a composite. However, to establish that a number is prime it needs to be checked for divisibility by each prime number up to the square root of the number. If the only factor found is 1, then it is a prime.
Is 15 and 30 prime or composite?
15 and 30 are both composite numbers because each has more factors than 1 and the number itself.
Are 15 and 24 prime number?
Neither 15 nor 24 are prime numbers. Each has more factors than 1 and the number itself.

Is 51 and 103 a composite or prime number?

Why should all the numbers be prime or composite?
Not all numbers are either prime or composite. The number 1/2 is neither prime nor composite. If you are referring only to the natural or counting numbers, note that every natural number is equal to the product of itself and 1 so each number has at least one divisor, itself. If it has no more divisors, then it is prime. If it has more than itself as a divisor, then it is composite.
How prime factorizations does a number have?
Each composite number has its own unique prime factorization.
Identify each number as a prime or composite number 13 33 45 19?

Is there another number that has the prime factorization of 2626?
No. Each composite number has its own unique prime factorization.
Tell whether each number is prime or composite or neither?
In theory it is possible but in practice, if a number is a product of two very large primes - each being a hundred digits long, or larger - then it is very difficult to tell whether it is prime or composite. The fact that it is so difficult makes this characteristic particularly useful for data encryption.
Are two composite number maybe relatively prime to each other?
