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 }
To find the greatest common factor (GCF) of 15 and 20 using the listing method, we first list the factors of each number. The factors of 15 are 1, 3, 5, and 15. The factors of 20 are 1, 2, 4, 5, 10, and 20. The common factor between both numbers is 5, so the GCF of 15 and 20 is 5.
