Set of all factors of 15 in Set builder method

Question

Set of all factors of 15 in Set builder method

Answer 1

This question has two parts:

1. Determining the factors of the number 15

2. Writing those factors as a set in set-builder notation

For Part 1, iterate through the set of numbers from 1 to 14; those that have 15 as a multiple are the factors of 15. For instance, 3 * 5 = 15, so 3 and 5 are factors of 15. Similarly, 1 * 15 = 15, so 1 is a factor of 15 (1 is a factor of every number).

For Part 2, write the factors as a comma-separated sequence, starting and ending with curly braces: {1, 3, 5}.
