Prime Factorization Concepts

The video tutorial from Moomoomath and Science explains the concept of prime factorization, which involves breaking down numbers into their prime factors. The tutorial demonstrates this process using the numbers 50 and 40. For 50, a factor tree is used to show that it can be expressed as 2 times 5 times 5. Similarly, the number 40 is broken down into 2 times 2 times 2 times 5. The video concludes with a call to action for viewers to subscribe for daily math and science content.
