To find the factorial of a number, multiply the number with the factorial value of the previous number. For example, to know the value of 6! multiply 120 (the factorial of 5) by 6, and get 720. For 7! multiply 720 (the factorial value of 6) by 7, get 5040. i.e., n! = n...

The combinations formula is used to easily find the number of possible different groups of r objects each, which can be formed from the available n different objects. Combinations formula is the factorial of n, divided by the product of the factorial of r, and the factorial of the difference...
The factorial formula is used to find the factorial of any number. It is defined as the product of the number with all its successive lowest value numbers till 1. Thus it is the result of multiplying the descending series of numbers. It must be remembered that the factorial of 0 is 1....
