A name given to the factors of a continued product when the former are derivable from one and the same function F(x) by successively imparting a constant increment or decrement h to the independent variable. Thus the product F(x).F(x + h).F(x + 2h) . . . F[x + (n-1)h] is called a factorial term, and its several factors take the name of factorials.
The product of the consecutive whole numbers from unity up to any given number; thus, 5 factorial is the product of 5 times four times three times two times one, or 120.
See Factorial number page.
the product of all the integers up to and including a given integer; "1, 2, 6, 24, and 120 are factorials"
a product of all positive whole numbers from the number one to a selected number
a series of multiplication based on a specific number
The expression n! (n factorial) is the product of all the numbers from 1 to n for any positive integer n.
the product of all whole numbers from down through 1, symbolized by . For example 3! = 3•2•1, or 6.
In math, the exclamation point means factorial! The factorial of a number is equal to the number times all the positive whole numbers less than it. For example, 5!= 5x4x3x2x1=120.
Any number factorial (written 3! Or 15!) means that you multiply that number by all the whole numbers less than that number. So 6! means 6*5*4*3*2*1.
In mathematics, the factorial of a positive integer n is the product of all positive integers less than or equal to n. This is written as n! and pronounced "n factorial", or colloquially "n shriek", "n bang" or "n crit". The notation n! was introduced by Christian Kramp in 1808.
