What else can I help you with?
Hwo do you determine if a number is prime or composite?
Prime numbers have two factors, composite numbers have more than two.
What is the prime and composite and how you determine?
Factor them. Prime numbers have two factors, composite numbers have more than two.
Do you need to know all of the factors of a number in order to determine if it prime or composite?
All natural numbers (counting numbers) greater than one are either prime or composite. If divisible by only one and the number itself, it is prime; if divisible by other natural numbers, then is composite. One is the only natural number that is neither prime nor composite.
How can you determine if a number is prime or composite or neither by looking at its factors of the number?
Prime numbers have two factors. Composite numbers have more than two. Numbers with less than two are neither.
Are prime numbers greater than 2 composite?
No. Prime numbers cannot be composite and composite numbers cannot be prime!
Why woul you determine prime factorization of only composite numbers?
Since prime numbers only have one prime factor (themselves), they don't have prime factorizations.
How can a factor tree help you determine if a number is prime or composite?
Prime numbers don't have factor trees. So if you can create a tree, your number's composite.
How do divisibility ryles help you to determine if a number is prime or composite?
If a number is divisible by 3 or more numbers than that number is composite, if not than it is prime.
How can you determine if a number is prime or composite?
Factor it. Prime numbers have two factors, composite numbers have more than two.
Does prime factorization of composite numbers include prime and composite numbers?
No, prime factorizations consist entirely of prime numbers.
Which numbers are prime numbers and which are composite numbers from 1 to 100?
1 is special 2 prime 3 prime 4 composite 5 prime 6 composite 7 prime 8 composite 9 composite 10 composite 11 prime 12 composite ext.
Why would you determine the prime factorization of only composite numbers?
Because the prime decomposition of primes is trivial and pointless.
