In the following exercises, find the prime factorization....

Key Concepts

Composite Number

A composite number is an integer greater than 1 that has more than two positive divisors. Understanding composite numbers is key in prime factorization, as it involves breaking down these numbers into the multiplication of prime numbers.

Prime Factorization

Prime factorization is the process of expressing a composite number as a product of its prime factors. It is a fundamental concept in number theory because it reveals the building blocks of any integer and has applications in various areas of mathematics including simplifying fractions and finding greatest common divisors.

Prime Number

A prime number is an integer greater than 1 that has no positive divisors other than 1 and itself. Primes are important because they serve as the basic ingredients in the arithmetic of integers, and every composite number can be uniquely represented as a product of prime numbers.

Divisibility Rules

Divisibility rules are heuristic shortcuts that help determine if one integer is divisible by another without performing long division. These rules are particularly useful in prime factorization as they assist in quickly identifying prime factors.

Factor Tree

A factor tree is a diagrammatic method used to break down a composite number into its constituent prime factors. It involves successive division by factors until all resulting factors are prime, making the process of prime factorization systematic and easier to visualize.
