To list all the factors of 30, we need to find all the numbers that divide evenly into 30. One way to find the factors is to divide 30 by each number from 1 to 30 and check if the division is exact, with no remainder.
Let's start listing the factors:
1 ÷ 30 = 30
2 ÷ 30 = 15
3 ÷ 30 = 10
4 ÷ 30 = 7.5 (not exact)
5 ÷ 30 = 6
6 ÷ 30 = 5
7 ÷ 30 = 4.2857 (not exact)
8 ÷ 30 = 3.75 (not exact)
9 ÷ 30 = 3.3333 (not exact)
10 ÷ 30 = 3
11 ÷ 30 = 2.7273 (not exact)
12 ÷ 30 = 2.5 (not exact)
13 ÷ 30 = 2.3077 (not exact)
14 ÷ 30 = 2.1429 (not exact)
15 ÷ 30 = 2
16 ÷ 30 = 1.875 (not exact)
17 ÷ 30 = 1.7647 (not exact)

23 ÷ 30 = 1.3043 (not exact)
24 ÷ 30 = 1.25 (not exact)
25 ÷ 30 = 1.2 (not exact)
26 ÷ 30 = 1.1538 (not exact)
27 ÷ 30 = 1.1111 (not exact)
28 ÷ 30 = 1.0714 (not exact)
29 ÷ 30 = 1.0345 (not exact)
30 ÷ 30 = 1
From our calculations, we can see that the factors of 30 are: 1, 2, 3, 5, 6, 10, 15, and 30.
