We may often need to use the Math & Trig functions in Excel for different calculating purposes. In this article, I’ll introduce you to one of them that is the **FACT **function in Excel.

The above screenshot is an overview of the **FACT **function. This article will guide you with easy examples to use the application of the **FACT **function.

**Introduction to the FACT Function**

The **FACT **function is a mathematical operator categorized under the **Math & Trig** function which is used to return the factorial of a number. Factorial of a number (n) can be calculated using the following formula:

**n!=1*2*3*……*(n-1)*n**

So the factorial of 5 will be-

**5!=5*4*3*2*1=120**

That means the factorial of a number is the multiplication of all the numbers decreased by 1 starting from the number and ending to 1.

**Purpose of the FACT Function: **

The **FACT **function is used to get the factorial of a number.

**Syntax:**

`=FACT(number)`

**Arguments:**

Arguments | Required/Optional | Explanation |
---|---|---|

number | Required | The nonnegative number for which we want the factorial. If the number is not an integer then it is truncated. |

**Returns:**

The factorial of a number.

## How to Use the Excel FACT Function: 2 Easy Examples

Let’s get introduced to our dataset first. I have used some integer, negative numbers, and non-numeric values in my dataset.

### Example 1: Excel FACT Function in Worksheet

Now we’ll find the factorial of each value from the range **B5:B12**.

**Steps:**

⏩ Activate **Cell C5**.

⏩ Then type the following formula given below in it-

`=FACT(B5)`

⏩ Later, press the **Enter **button for the output.

Then you will get the factorial for 0 is 1.

To get the factorials for the other values just drag the **Fill Handle** icon.

Now you get all the factorials for the numbers like the image below. Take a look at the output that there are two errors. The **FACT **function will return **#NUM** if the given number is less than 0. It will show **#VALUE** if it finds a non-numeric value. And if the given number is not an integer then it will truncate the decimal portion that’s why the factorials of 4 and 4.5 are the same.

### Example 2: FACT Function with Keyboard Shortcut

We can calculate the factorial of a number using the **FACT **function in a different way. Here, we’ll use a keyboard shortcut with the **FACT **function. Let’s see how to do it.

**Steps:**

⏩ Write the following formula in **Cell C4**–

`=FACT(`

⏩ Then press **Ctrl+A** on your keyboard.

A dialog box will open up.

⏩ Type the number in the **Number **box.

⏩ Finally, just press **OK**.

Then you will see that the factorial is calculated.
