## Prime Factorization

• Factorization is the process of finding the prime factors of a given number. The prime factors are the individual numbers that can be multiplied together to produce the given number. The prime factorization of a number is a unique representation of the number as a product of its prime factors.
• The prime factorization of a number can be found by dividing the number by its prime factors. The prime factors can be found by dividing the number by each prime number until the number is divided by 1. The prime factors can also be found by using the prime factorization theorem.
• The prime factorization theorem states that the prime factorization of a number is the product of its prime factors in ascending order. The ascending order of the prime factors is the order in which the prime factors are listed when the number is written in descending order.
• The prime factorization of a number can be used to find the greatest common factor (GCF) and the least common multiple (LCM) of two numbers. The GCF is the largest number that can be divided by both numbers without leaving a remainder. The LCM is the smallest number that can be multiplied by both numbers without leaving a remainder.
• The prime factorization of a number is also used to find the perfect square root of a number. The perfect square root of a number is the largest number that can be multiplied by itself to produce the given number. The perfect square root of a number can be found by taking the square root of the product of the prime factors of the number.
