The arrangement of dots shows three groups of 6 dots each, which is 3 x 6 = 18. The arrangement also shows a 3x3 grid which is 9 dots, and a 2x4 arrangement which is 8 dots. The question seems to be asking about the total number of dots in these separate arrangements, not a single number represented by dots.

Let's assume the question is asking for factors of 18 based on the first arrangement.

• The factors of 18 are 1, 2, 3, 6, 9 and 18.
• 18 is a composite number.

If the question is asking about the 9 dots:

• The factors of 9 are 1, 3 and 9.
• 9 is a composite number.

If the question is asking about the 8 dots:

• The factors of 8 are 1, 2, 4 and 8.
• 8 is a composite number.

Since the line for factors has 6 spaces, it is most likely asking about the number 18.
