Multiples and Factors

The video tutorial explains the concepts of factors and multiples using the number 24 as an example. It describes how 24 is a multiple of its factors, including 1, 2, 3, 4, 6, 8, 12, and 24, and introduces the idea of composite numbers, which have more than two factors. The tutorial contrasts this with prime numbers, which have only two factors: 1 and the number itself, using 17 as an example. The lesson concludes by reinforcing the understanding that a number is a multiple of all its factors.
