Throughout this article, you will learn how to calculate the factorial of 100 in a step-by-step manner, explaining how it is calculated.
To find
The factorial of 100
Step-by-step explanation
When n is a positive number, its factorial can be written as follows
n! = n × (n – 1) × (n – 2) × (n – 3) × … … × 1
Here our given number is 100. Thus taking n = 100, we get
100! = 100 × (100 – 1) × (100 – 2) × (100 – 3) × … … × 1
= 100 × 99 × 98 × 97 × … … × 1
= 93326215443944152681699238856266700490715968264381621468592963895217599993229915608941463976156518286253697920827223758251185210916864000000000000000000000000
Let us find the factorial of a smaller number. Say, n = 4. Then 4! = 4 × 3 × 2 × 1 = 24.
Answer:
100! = 93326215443944152681699238856266700490715968264381621468592963895217599993229915608941463976156518286253697920827223758251185210916864000000000000000000000000
The approximate 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.
