Use a diagram to list the factor pairs of each number

I don't know what you mean by diagram but for
1 here is the answer.

1) factors of 18: 1, 2, 3, 6, 9, 18 (because 1 x 18 =18, 2 x 9 = 18, 3 x 6 = 18. )

2) factors of 52: 1, 2, 4, 13, 26, 52 (because 1 x 52 = 52, 2 x 26 = 52, 4 x 13 = 52. )

3) (Idk, so sorry! :c )

4) 402

5) 36

6) 32

7) (Last but not least)

I hope I helped. I'm not very good at math xD

What is the inequality?
