| What is the factorial of hundred |
Introduction
In this Mathemitical world, factorials are an fascinating concept. They provide us with a path to calculate the product of an integer and all the positive integers. When it comes to the factorial of hundred, we are dealing with a remarkable number with significant implications.
What is a Factorial?
Before delving into the factorial of a hundred, let's first understand what a factorial is. Factorial is denoted by the symbol exclamation mark (!). For any positive integer n, n factorial is the product of all positive integers less than or equal to n. It is represented as n! For example, 10 factorial is written as 10! and calculated as 10 x 9 x 8 x 7x 6 x 5 x 4 x 3 x 2 x 1, which equals 3628800.

The Magnitude of the Factorial of Hundred
Now, let's explore the factorial of a hundred. Computing such a massive factorial may seem dismaying, but it has a fascinating value. The factorial of hundred, written as 100!, is the product of all positive integers from 1 to 100.
To calculate 100!, we need to multiply all these numbers together. As you can imagine, this results in an immensely large number that stretches over 24 digits.
The exact value is:
100! =9,332,621,544,394,415,268,169,923,885,626,670,049,071,596,826,438,162,146,859,296,389,521,759,999,322,991,560,894,146,397,615,651,828,625,369,792,082,722,375,825,118,521,091,686,400,000,000,000,000,000,000,000
