What are the uses of prime and composite numbers?
All composite numbers have prime factors and these are used to find the highest common factor of 2 or more numbers and they are also used in finding the lowest common multiple of 2 or more numbers. Composite numbers have 2 or more factors while prime numbers have only 2 factors which are themselves and one
What is meant by finding the common factors of two or more numbers?
Finding those numbers which divide exactly (with no remainder) into all of the two or more numbers.
How can you find that 32 and 95 are not prime number without finding it factors?
Because 32 is divisible by 2 and 95 is divisible by 5 meaning that they both have more than two factors which makes them composite numbers.
Is 405 composite or prime?
405 is composite. Anything that is divisible by more than two numbers (itself and 1) is considered a composite number. Looking at the number, you can tell that it is divisible by 5 because it ends in a 5. There will be more factors, but finding one that is not 1 or itself will cause the number to be composite.
Why are prime numbers on the bottom of a factor tree?
Factor trees are ways of notating the process of finding the prime factorization of a given composite number and, as such, should result in an identifiable string of prime factors.
What are the prime factorization for composite numbers 1-100?
finding the prime factors of a composite number
Do you need to know all of the factors of a number in order to determine if it is a prime or composite?
Yes, you do. And know them well, or else you'll get it wrong! Well, not exactly. To determine that a number is prime you need to know that the number has exactly two factors, which means that there are no other factors. You know that a number is composite by finding just one factor that is neither one nor the number itself.
How is prime factorization different from finding factors of a number?
All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. When finding the factors of a number, you find all the factors. The prime factorization is a multiplication string of just prime factors that will total the given number.
Input a number'calculate it is prime or composite?
In general, it is not possible. Composite and primes can be infinitely large and finding possible factors or proving that there are none is not always possible.
What lists factors is it called common factors or composite number or multiple?
When you are finding common factors, one method is to list the factors.
What are the uses of prime and composite numbers?

What is meant by finding the common factors of two or more numbers?
Finding those numbers which divide exactly (with no remainder) into all of the two or more numbers.
What area in maths is closest to code breaking?
Probably prime factorisation: finding two very large prime factors of an even larger composite.
What is the name of Eratosthenes' method of finding composite numbers?
Eratosthenes' method of finding prime and composite number is called 'The Sieve of Eratosthene'.
What is the difference between finding all possible factors of 24 and finding the prime factorization of 24?
1, 2, 3, 4, 6, 8, 12, 24 2 x 2 x 2 x 3 = 24 The factors include composite numbers.
How can you find that 32 and 95 are not prime number without finding it factors?
Because 32 is divisible by 2 and 95 is divisible by 5 meaning that they both have more than two factors which makes them composite numbers.
