Factors don't have numbers. Numbers have factors.
Numbers that have the factors 2, 4 and 8 are 8 and all of its multiples.
The numbers are: 8 16 and 24
All composite numbers have more than two factors. The smallest such number is 4, which is equal to 2 x 2. 4 has three factors: 1, 2, and 4.

8, 88, 808808088 are three examples.
They are: 8, 16 and 24
1, 2 and 4
Three factors
What two numbers have the factors 2 4 and 8
Four only has three factors: 1, 2 and 4. For any of them to be a GCF, they need to be compared to another set of numbers.
Calculate the least common multiple of the three numbers. Any multiple of that has all those numbers as factors.
