Well, darling, the number you're looking for is 15. It's less than 20, odd, and can be broken down into the prime factors 3 and 5. So, there you have it, a prime factor party with the number 15 strutting its stuff.
A prime number only has two factors. If the number you're looking at has more than two factors, it is not prime.
A prime number is any number that only has one and itself as factors. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
A prime number is any number that only has one and itself as factors. Therefore, any number that has more than two factors is not prime. Check the the factors of a number to tell if it is prime or not.
A number is prime when it only has one and itself as factors is prime. Therefore, to tell if a number is prime or composite simply find it's factors. If it has more than two factors than it is not a prime number, it is composite.
Numbers can be checked to see if they are primes simply by factoring them. Every prime number has exactly two factors, 1 and the number itself. If there are more or less than 2 factors, the number is not a prime. 1 has only one factor so it is not a prime, and composite numbers have 3 or more factors.
There is not such a thing as a composite prime number. A prime number has exactly two factors. A composite number has more than two factors.
Prime numbers have two factors. Composite numbers have more than two. Numbers with less than two are neither.
