The video tutorial covers the concept of factors, explaining that factors are whole numbers multiplied to get a product. It uses examples like 30 and 18 to demonstrate how to find factors by listing number pairs. The tutorial also applies this knowledge to a real-world problem, where Bob is building a deck and needs to determine possible dimensions using factors of 48. The lesson concludes with a transition to the next topic, prime factorization.

How do you find all factors of a number?

• By dividing pairs of numbers

• By subtracting pairs of numbers

• By multiplying pairs of numbers

Why do we stop listing factors at 5 times 6 for the number 30?

• Because 5 is the largest factor

• Because factors start repeating

• Because 30 is a prime number

• Because 6 is not a factor

What are the factors of 18?

• 1, 2, 3, 6, 9, 18

Why do we list each factor only once?

• To save space

• To avoid confusion

• To prevent repetition

• To make it easier to read

What is the purpose of using a diagram to show factor pairs?
