Basically, factorial function is useful in computing the number of combinations or permutations that can be constructed from a set of objects. What is Factorial? The product of an integer and all the integers below it; e.g. factorial four ( 5! ) is equal to 120.(i.e 5*4*3*2*1 = 120) Symbol of Factorial is:! Example: 7! (Find Factorial of 7?)

The aproximate value of 100! is 9.3326215443944E+157. The number of trailing zeros in 100! is 24. The number of digits in 100 factorial is 158. The factorial of 100 is calculated, through its definition, this way: 100! = 100 • 99 • 98 • 97 • 96 ... 3 • 2 • 1

For example, ! =! = =. Factorial of zero. The factorial of is , or in symbols, ! =. There are several motivations for this definition: For =, the definition of ! as a product involves the product of no numbers at all, and so is an example of the broader convention that the empty product, a product of no factors, is equal to the multiplicative identity.; There is exactly one permutation of zero ...

70! is approximately 1.197857... x 10 100, which is just larger than a Googol (the digit 1 followed by one hundred zeros). 100! is approximately 9.3326215443944152681699238856 x 10 157. 200! is approximately 7.8865786736479050355236321393 x 10 374

The factorial of a number is the function that multiplies the number by every natural number below it. Symbolically, factorial can be represented as "!". So, n factorial is the product of the first n natural numbers and is represented as n! So n! or "n factorial" means: n! = 1.

In short, a factorial is a function that multiplies a number by every number below it till 1. For example, the factorial of 3 represents the multiplication of numbers 3, 2, 1, i.e. 3! = 3 × 2 × 1 and is equal to 6. In this article, you will learn the mathematical definition of the factorial, its notation, formula, examples and so on in detail.

Jul 31, 2021 · Factorial of a non-negative integer, is the multiplication of all integers smaller than or equal to n. For example factorial of 6 is 6*5*4*3*2*1 which is 720. We have discussed simple program for factorial .

n! means n × (n − 1) × ... × 3 × 2 × 1. For example, 10! = 10 × 9 × ... × 3 × 2 × 1 = 3628800, and the sum of the digits in the number 10! is 3 + 6 + 2 + 8 + 8 + 0 + 0 = 27. Find the sum of the digits in the number 100!

factorial(1) → 1 factorial(2) → 2 factorial(3) → 6. Go...Save, Compile, Run (ctrl-enter) Show Hint Show Solution

We've used long instead of int to store large results of factorial. However, it's still not big enough to store the value of bigger numbers (say 100). For results that cannot be stored in a long variable, we use BigInteger variable declared in java.math library. Example 2: Find Factorial of a number using BigInteger
