How to find the prime factorization of a composite number.
Practice this chapterHow to find the prime factorization of a composite number. Find two factors whose product is the given number, and use these numbers to create two branches
If a factor is not prime, write it as the product of two factors and continue the process Divisibility Tests A number is divisible by: 2 if the last digit is 0, 2, 4, 6, or 8.
composite number — A composite number is a counting number that is not prime. It has factors other than 1 and the number itself. prime factorization — The prime factorization of a number is the product of prime numbers that equals the number. number — divisible by: 2 if the last digit is 0, 2, 4, 6, or 8. factors — If a · b = m , then a and b are factors of m.

What does “composite number” mean in Foundations?
- 1Use the wording this chapter gives for composite number.
- 2The book says: A composite number is a counting number that is not prime. It has factors other than 1 and the number itself.
- 3Do not use the meaning of prime factorization. That term means The prime factorization of a number is the product of prime numbers that equals the number.
Result: A composite number is a counting number that is not prime. It has factors other than 1 and the number itself
Why. That is the meaning this chapter gives for composite number.
Do not swap composite number and prime factorization. composite number means A composite number is a counting number that is not prime. It has factors other than 1 and the number itself. prime factorization means The prime factorization of a number is the product of prime numbers that equals the number.
