Finding Factor Pairs

The video tutorial explains the concept of factors and factor pairs, using the numbers 16 and 25 as examples. It demonstrates how to find all possible factor pairs for these numbers by using a number line. For 16, the factor pairs are 1 and 16, 2 and 8, and 4 and 4, with factors being 1, 2, 4, 8, and 16. For 25, the factor pairs are 1 and 25, and 5 and 5, with factors being 1, 5, and 25. The lesson emphasizes understanding the multiplication of factors to achieve the original number.
