Factorials are a fundamental concept in mathematics, playing a key role in combinatorics, probability, and various algorithms. Whether you’re solving permutations, computing growth rates, or working on coding problems, understanding factorial values is essential. In this article, we break down the factorial calculations for the numbers 10, 4, 5, and 1—10! = 3,628,800, 4! = 24, 5! = 120, and 1! = 1—and explore why these values matter.
Understanding the Context
What Is a Factorial?
The factorial of a positive integer \( n \), denoted \( n! \), is the product of all positive integers from 1 to \( n \). Mathematically,
\[
n! = n \ imes (n-1) \ imes (n-2) \ imes \cdots \ imes 2 \ imes 1
\]
- For example:
\( 5! = 5 \ imes 4 \ imes 3 \ imes 2 \ imes 1 = 120 \)
\( 4! = 4 \ imes 3 \ imes 2 \ imes 1 = 24 \)
\( 10! = 10 \ imes 9 \ imes \cdots \ imes 1 = 3,628,800 \)
\( 1! = 1 \) (by definition)

Breaking Down the Key Examples
1. \( 10! = 3,628,800 \)
Calculating \( 10! \) means multiplying all integers from 1 to 10. This large factorial often appears in statistical formulas, such as combinations:
\[
\binom{10}{5} = \frac{10!}{5! \ imes 5!} = 252
\]
Choosing 5 items from 10 without regard to order relies heavily on factorial math.

2. \( 4! = 24 \)
\( 4! \) is one of the simplest factorial calculations and often used in permutations:
\[
P(4, 4) = 4! = 24
\]
This tells us there are 24 ways to arrange 4 distinct items in order—useful in scheduling, cryptography, and data arrangements.
3. \( 5! = 120 \)
Another commonly referenced factorial, \( 5! \), appears in factorial-based algorithms and mathematical equations such as:
\[
n! = \ ext{number of permutations of } n \ ext{ items}
\]
For \( 5! = 120 \), it’s a handy middle-point example between small numbers and larger factorials.
4. \( 1! = 1 \)
Defined as 1, \( 1! \) might seem trivial, but it forms the base case for recursive factorial definitions. Importantly:
\[
n! = n \ imes (n-1)! \quad \ ext{so} \quad 1! = 1 \ imes 0! \Rightarrow 0! = 1
\]
This recursive property ensures consistency across all factorial values.
