8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 8!
5 factorial = 5*4*3*2*1 = 120
A factorial is a whole number multiplied by all the whole numbers less than that number. So 3 factorial (written as 3!) is 3 times 2 times 1=6
2*3*4 - 1 = 23 and 2*3*4 + 1 = 25 and not a factorial in sight! Oops.. sight.
Let's take the example of finding the factorial of a number (of a positive integer). The factorial of N is N * (N-1) * (N-2) * (N-3) ... * 3 * 2 *1 It is the product of all integers between that number (including that number) and 1. For example, factorial 2 = 2*1 = 2 factorial 3 = 3*2*1 = 6 factorial 4 = 4*3*2*1= 24 Now you define a recursive function Fac (N) as Fac (N) = Fac (N-1) * N, with Fac(1) predefined as 1. Thus, Fac(N-1) = Fac(N-2) * (N-1) and Fac(N-2) = Fac(N-3) * (N-2) and thus recursion takes over until such time fac(1) needs to be evaluated. We know the value of Fac(1) which is set as 1. Thus we can evaluate Factorial(N) using recursion.
Factorial for number N is N x N-1 x N-2 X N- (N-1). e.g. if you need to calculate factorial for 5 then compute 5 x 4 x 3 x 2 x 1.
3! = 3×2×1 = 6
It can be written in factorial form as 6! Thereafter you can find its value as 6! = 6 x 5 x 4 x 3 x 2 x 1 = 720.
8! means 8*7*6*5*4*3*2*1=40,320
3! = 3*2*1 = 6
That's not the factorial of any number. For a start, the factorial of any number greater than or equal to 2 is even, because of the factor 2. The factorial of any number greater or equal to five ends with 0. Another answer: I suspect the questioner meant to ask how to write 8*7*6*5*4*3*2*1 as a factorial. If so, then the answer is "8!"
5 factorial = 5*4*3*2*1 = 120
8!
It represents a factorial. A factorial is when you take each number up to value and multiply them. So factorial 3 is 1 x 2 x 3. Factorial 7 is 1 x 2 x 3 x 4 x 5 x 6 x 7.
No, that is nothing like a factorial. 4 factorial (written as 4!) is 4*3*2*1 = 24.
3! = 3 x 2 x 1 = 6
A factorial is a whole number multiplied by all the whole numbers less than that number. So 3 factorial (written as 3!) is 3 times 2 times 1=6
2*3*4 - 1 = 23 and 2*3*4 + 1 = 25 and not a factorial in sight! Oops.. sight.
