From Wikipedia the free encyclopedia In mathematics Legendres formula gives an expression for the exponent of the largest power of a prime p that divides the factorial n. It still follows the rule that the factorial of any number is that number times the factorial of 1 smaller than that number because 32. And calculated by the product of integer numbers from 1 to n.
Factorials are also used extensively in probability theory and number theory.
For the integer greater than or equal to one the factorial formula is mathematical is generalized as given below. N n 1. The factorial formula or formula for n factorial is given by n. Here are some half-integer factorials.
