You can divide both 4 and 8 by a common factor of $$ \square $$

Question

UpStudy AI · Accepted Answer

Both **4** and **8** share several common factors. A **common factor** is a number that divides two or more numbers without leaving a remainder. To find a common factor for 4 and 8, you can list the factors of each number and identify the numbers that appear in both lists.

### Factors of 4:
- 1
- 2
- 4

### Factors of 8:
- 1
- 2
- 4
- 8

### Common Factors of 4 and 8:
- **1**
- **2**
- **4**

So, you can divide both 4 and 8 by **1**, **2**, or **4**.

**Example:**
Let's choose **2** as the common factor.

- Dividing 4 by 2: $$ \frac{4}{2} = 2 $$
- Dividing 8 by 2: $$ \frac{8}{2} = 4 $$

Therefore, replacing the blank:

*You can divide both 4 and 8 by a common factor of **2**.*

**Alternatively**, using the greatest common factor (**4**):

- Dividing 4 by 4: $$ \frac{4}{4} = 1 $$
- Dividing 8 by 4: $$ \frac{8}{4} = 2 $$

So, you can also say:

*You can divide both 4 and 8 by a common factor of **4**.*

Choosing the greatest common factor can be particularly useful for simplifying ratios or fractions.
You can divide both 4 and 8 by 2 or 4.
