👉 Unifactorial, also known as a unit factorial, is a mathematical concept used in statistics and probability theory. It refers to the number of factors that divide a given number n exactly.
For example, if we want to know how many factors are there in 10! (the factorial of 10), we would calculate this by dividing 10 by each factor from 2 to 10:
- Factorial(2) = 2
1 =
