This calc multiplies together all the whole numbers up to the input number n to give the factorial of n (=n!). It can also perform the inverse function, finding the number x that produces a factorial (x!) that you enter.

Prime factorization

The prime factors of a number are prime numbers by which the number is divisible. They are found here by testing division by increasingly large numbers. If all the numbers in the output boxes are multiplied together, then the result will be the input number.

Random number

This calc generates random numbers from 1 up to and including a maximum of your choice. Each time you press "calculate", a new number is generated.
