FACT
The FACT function calculates the factorial of a number, which is the product of all positive integers up to that number. It is used in mathematics and statistics for permutations and combinations.
Syntax 🔗
=FACT(number)
number | The non-negative number for which you want to calculate the factorial. |
About FACT 🔗
The FACT function in Excel helps you calculate the factorial of a given number. Factorials are important in permutations, combinations, and various mathematical operations. To use FACT, simply input the number for which you need the factorial. This function provides an easy way to obtain factorial values without manual calculations, making your mathematical tasks more efficient in Excel.
Examples 🔗
To calculate the factorial of 5, use the formula:
=FACT(5)
This returns 120, the factorial value of 5.
To find the factorial of 7, use:
=FACT(7)
Excel returns 5040, the factorial value of 7.
Notes 🔗
Ensure the number you provide to the FACT function is non-negative, as factorials are only defined for non-negative integers. An error may occur if you input a negative number.
Questions 🔗
A factorial is the product of all positive integers up to a given number. For example, the factorial of 5 (5!) is calculated as 5 x 4 x 3 x 2 x 1 = 120. The FACT function automates this calculation in Excel.
Can I calculate factorials for decimal numbers using the FACT function?No, the FACT function is designed to calculate factorials for non-negative integers. It does not support decimal numbers or fractions.
What happens if I input a negative number into the FACT function?The FACT function will return an error if a negative number is provided as input, as factorials are not defined for negative integers.
