Краткое описание слова + примеры использования
**Факториал** — это произведение всех натуральных чисел от 1 до данного числа.
Вот несколько примеров использования слова **«factorial»** в английском языке:
1. To find the factorial of a number, you multiply all the numbers from 1 to that number. For example, **5!** (five factorial) is equal to **5 x 4 x 3 x 2 x 1**, which is **120**.
2. In mathematics, the factorial of a non-negative integer **n** is denoted by **n!** and is equal to the product of all positive integers less than or equal to **n**. For example, **3!** is equal to **3 x 2 x 1**, which is **6**.
3. The factorial operation is used in combinatorics to calculate the number of ways to arrange or permute a set of objects. For example, if we have **4** objects, then **4!** is equal to **4 x 3 x 2 x 1**, which is **24**, and represents the number of ways we can arrange these **4** objects.
