Do you know the definition of " n! " ?silverstar said:Hi, question to @HallsofIvy, what is the procedure if the number is not wholly divisible at some point. For example you take the number 5 and try to divide it by 2, you get 2 remainder 1. How would you proceed from here? I vaguely remember doing something with the remainder, but don't remember what it was. Searching on google has not produced the results I'm seeking. Please let me know if you know of a good resource for this or if you know how to proceed. Thank you in advance!
abhishek ghos said:what you can do for big n is to apply stirling approximation
ln(n!)=(n*ln(n)) - n
so you can make a handy table or chart to pluck up the corresponding n values, apart from that doing this is a real mess.
An unknown factorial is a mathematical problem where you are given the value of a factorial expression and you have to find the value of the unknown number.
To solve an unknown factorial, you can use various methods such as using the inverse of the factorial function, using algebraic manipulation, or using a calculator or computer program.
Some tips for solving an unknown factorial include trying different methods, breaking the problem into smaller parts, and checking your solution to make sure it satisfies the given factorial expression.
Yes, an unknown factorial can have more than one solution. This can happen when the given factorial expression has multiple factors or when there are multiple ways to simplify the expression.
Unknown factorials are used in various fields such as physics, engineering, and computer science to solve problems involving combinations and permutations, as well as in probability and statistics to calculate probabilities and combinations. They are also used in cryptography and coding theory to generate secure codes and in machine learning algorithms.
