Find the mean of all factors of 10.

Answer

To find the mean of all factors of 10, we can follow these steps:

### Step 1: Identify the factors of 10
The factors of a number are the integers that can be multiplied together to yield that number. For 10, we can find the factors as follows:
- 1 × 10 = 10
- 2 × 5 = 10

Thus, the factors of 10 are: **1, 2, 5, and 10**.

### Step 2: List the factors
Now we can list the factors we found:
- Factors of 10: **1, 2, 5, 10**

### Step 3: Calculate the sum of the factors
Next, we need to find the sum of these factors:
- Sum = 1 + 2 + 5 + 10

Calculating this gives:
- Sum = 1 + 2 = 3
- Sum = 3 + 5 = 8
- Sum = 8 + 10 = 18

So, the sum of the factors is **18**.

### Step 4: Count the number of factors
Now we count how many factors there are:
- Total number of factors = 4 (since we have 1, 2, 5, and 10)

### Step 5: Calculate the mean
The mean is calculated by dividing the sum of the factors by the total number of factors:
- Mean = Sum of factors / Total number of factors
- Mean = 18 / 4

Calculating this gives:
- Mean = 4.5

### Final Answer
The mean of all factors of 10 is **4.5**.
