Understanding Factors of Numbers

This tutorial demonstrates how to find the factors of a number using a T-table method. It begins with an example of finding the factors of 48 by listing pairs of numbers that multiply to 48. The process involves checking divisibility by numbers starting from 1 and moving upwards. The tutorial then provides another example with the number 36, following a similar method to identify its factors. The video emphasizes logical reasoning and basic multiplication facts to determine factor pairs.
