Step-by-step explanation:

Extra explanation on what a factor is, I don't know how to explain it but here are some examples:

Example:

Find factors of 12

1 x 12 = 12

2 x 6 = 12

3 x 4 = 12

So. 1, 2, 3, 4, 6 and 12 are factors of 12 basically.

the aswere is the one with all 8's and the second one is with the 10,8 and 6
