Understanding Prime Numbers and Factorization

The video tutorial explains prime factorization by first defining factors and prime numbers. It uses the number 12 to illustrate how to find factors and then identifies which of these are prime. The concept of prime numbers is clarified with examples, and the process of prime factorization is demonstrated by expressing 12 as a product of its prime factors.

What are the two key concepts needed to understand prime factorization?

• Addition and subtraction

• Prime numbers and factors

• Multiplication and division

• Even and odd numbers

Which of the following is a factor of 12?

How can the number 12 be expressed as a product of two numbers?

• 3 * 5

• 2 * 6

• 4 * 5

• 1 * 7

What defines a prime number?
