Exploring Multiples, Factors, and Number Types

The video tutorial covers the concepts of multiples, factors, prime numbers, and composite numbers. It begins by defining multiples as products of a number and a whole number, using the example of the first five multiples of three. The tutorial then explains factors as numbers that multiply to form another number, illustrated with the factors of 12. Prime numbers are defined as numbers with exactly two factors, with examples like 3, 11, and 17. Finally, composite numbers are described as having more than two factors, using 24 as an example.
