Final answer:
The set that contains all the factors of 12 is option a. (1,2,3,4,6,12).
Step-by-step explanation:
The set that contains all the factors of 12 is option a. (1,2,3,4,6,12).
To find the factors of 12, we need to find the numbers that divide evenly into 12 without leaving a remainder. We can start by listing all the numbers from 1 to 12 and determining which ones divide evenly into 12. The numbers that divide evenly into 12 are 1, 2, 3, 4, 6, and 12.
For example, 2 is a factor of 12 because 12 divided by 2 equals 6 with no remainder. Option a
