Write all the factors of the following numbers : (a)   24       (b)  15         (c)   21(d)  27         (e)  12         (f)   20(g)   18        (h)  23         (i)   36

Explanation

To find all the factors of the given numbers, we will systematically check each number to see which integers divide it evenly (without leaving a remainder).

### Step-by-Step Solution:

**(a) Factors of 24:**
1. Start with 1: \( 1 \times 24 = 24 \)
2. Check 2: \( 2 \times 12 = 24 \)
3. Check 3: \( 3 \times 8 = 24 \)
