A factorial is a function that multiplies a number by every number below it. For example 5!= 5*4*3*2*1=120.
What is a Factorial?
- 2 factorial is 2! = 2 x 1 = 2.
- 4 factorial is 4! = 4 x 3 x 2 x 1 = 24.
- 5 factorial is 5! = 5 x 4 x 3 x 2 x 1 = 120.
- 0 factorial is a definition: 0! = 1.

Can you multiply factorials?
Factorials, denoted by a.You can also multiply factorials by hand. The easiest way to do it is to calculate each factorial individually, and then multiply their products together. You can also use certain rules of factorials to pull out common factors, which can simplify the multiplication process.
How do you do Factorials in math?
In simpler words, the factorial function says to multiply all the whole numbers from the chosen number down to one. In more mathematical terms, the factorial of a number (n!) is equal to n(n-1). For example, if you want to calculate the factorial for four, you would write: 4!

Can you distribute factorials?
A factorial distribution happens when a set of variables are independent events. In other words, the variables don’t interact at all; Given two events x and y, the probability of x doesn’t change when you factor in y. Therefore, the probability of x, given that y has happened —P(x|y)— will be the same as P(x).
