What Is A Factorial Of Hundred?

Are you curious to know what is a factorial of hundred? You have come to the right place as I am going to tell you everything about a factorial of hundred in a very simple explanation. Without further discussion let’s begin to know what is a factorial of hundred?

What Is A Factorial Of Hundred?

In the realm of mathematics, factorial is a fundamental operation that has various applications in fields like combinatorics, probability theory, and calculus. One of the most colossal factorial calculations that has intrigued mathematicians and enthusiasts alike is the factorial of one hundred, denoted as “100!” In this blog post, we will explore what a factorial is, how to calculate the factorial of one hundred, and the significance of such a vast number in mathematics.

What Is A Factorial?

A factorial is a mathematical operation denoted by the exclamation mark (!) and is applied to a non-negative integer. It represents the product of all positive integers from 1 up to that integer. For example:

5! (read as “five factorial”) = 5 × 4 × 3 × 2 × 1 = 120

10! = 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 3,628,800

The Factorial of One Hundred (100!)

The factorial of one hundred, written as “100!”, is a staggering number. Calculating it manually would be an exceptionally time-consuming task. However, with the help of modern technology and mathematical software, we can determine its value:

100! = 93,326,215,443,944,152,681,699,238,856,266,700,490,715,968,264,381,621,468,592,963,895,217,599,993,229,915,608,941,463,976,156,518,286,253,697,920,827,223,758,251,185,210,916,864,000,000,000,000,000,000

As you can see, the factorial of one hundred is an enormously large number with 24 digits, and it grows rapidly as the input number increases.

Significance In Mathematics And Combinatorics

Factorials find applications in various mathematical and combinatorial problems:

  1. Permutations and Combinations: Factorials are used to calculate the number of permutations (arrangements) and combinations (selections) of elements from a set. They are essential in probability theory and statistics.
  2. Taylor Series: Factorials are involved in the expansion of functions as Taylor series, which is crucial in calculus and mathematical analysis.
  3. Combinatorial Identities: Factorial expressions are part of numerous combinatorial identities and formulas used in solving problems related to counting and arrangements.
  4. Probabilistic Distributions: Factorials are employed in determining the probabilities of various outcomes in experiments and events.


The factorial of one hundred, represented as “100!”, is a colossal number that demonstrates the power and complexity of mathematical operations. While manually calculating such a factorial would be practically impossible, modern computational tools allow us to explore the vast world of mathematics and combinatorics, where factorials play a pivotal role. The significance of factorials extends far beyond this single example, as they are fundamental in solving a wide range of mathematical problems and real-world applications.


What Is The Fractional Of 100?

Thus, the required fraction will be 100 / 1.

Any number can be represented in the form of a fraction.

What Is 4 Factorial Equal To?

That means, the factorial of 4 gives the required number of ways, i.e. 4! = 4 × 3 × 2 × 1 = 24.

What Is A Factorial Of 9?

The factorial of a number is the product of all the natural numbers from 1 to that number. The factorial of any number ‘n’ is represented as n! Thus, the factorial of 9 is 362,880.

What Is Factorial (– 1?

The factorials of negative real numbers are complex numbers. At negative integers the imaginary part of complex factorials is zero, and the factorials for -1, -2, -3, -4 are -1, 2, -6, 24 respectively. Similarly, the factorials of imaginary numbers are complex numbers.
