Factors and Multiples
Finding factors and multiples of numbers helps solve many mathematical problems. It is also very useful when working with fractions e.g. adding 1/3 and 1/2.
This section includes explanations of what factors and multiples are, prime numbers and composite numbers.
Select from the links above or from the menu options to learn more about factors and multiples.
There are also worked examples showing how to do prime factorization using factor trees as well using the greatest common factor to solve problems.
