To find the GCF or the LCM of a set of numbers, it is sometimes practical to write out lists of the factors or multiples as the case may be and compare them. This is known as the listing method.

1) listing method: { 1,2,3} rule method: {x| x is a positive whole number less than four} 2) listing method: { 2,4,6,8,....}. rule method: {x| x is a positive even number }
Two methods to solve a greatest common factor (GCF) problem are the prime factorization method and the listing method. In the prime factorization method, you find the prime factors of each number and determine the common factors. The GCF is the product of the common prime factors. In the listing method, you list the factors of each number and find the common factors. The GCF is the greatest common factor from the common factors list.
