What is the value of (n!) by formula?

Answer 1

Zoe Adams

Please see below.

#n# factorial is given by

#n! =nxx(n-1)xx(n-2)xx........xx3xx2xx1#

it can also be written as

#n! = nxx(n-1)!#

#1! =1#

#2! =2xx1=2#

#3! = 3xx2xx1=6#

#4! = 4xx3xx2xx1=24#

#5! =5xx4xx3xx2xx1=120#

#6! =6xx5xx4xx3xx2xx1=720# and so on.

The value of (n!) (n factorial) by formula is:

[n! = n \times (n - 1) \times (n - 2) \times \ldots \times 2 \times 1]

In other words, (n!) is the product of all positive integers from (1) to (n).
