What is prime factorization of a number or expression

The video tutorial explains prime factorization, which involves rewriting a number or expression as a product of its prime factors. It uses the number 12 as an example, showing different ways to factor it and ultimately breaking it down into its prime factors using a factor tree. The prime factorization of 12 is demonstrated as 2 times 2 times 3.

What is the main goal of prime factorization?

• To determine if a number is even or odd

• To find the sum of all factors of a number

• To express a number as a product of its prime factors

• To calculate the square root of a number

Which of the following is a composite number?

• 3

• 2

• 5

Which pair of numbers are both prime factors of 12?

• 6 and 2

• 2 and 3

• 12 and 1

• 4 and 3

What is the first step in creating a factor tree for the number 12?

• Divide 12 by 1

• Express 12 as 4 times 3

• Multiply 12 by 2

• Subtract 3 from 12

What is the prime factorization of 12?

• 6 x 2
