## Check if the given number is a prime number

Any number which cannot be divisible by any other number except one and itself is called a prime number. In other words, any number which doesn't have more than 2 factors (1 and itself) is called a prime number.

Examples: 2, 3, 11, 13, 19 and such

For a given number n, we shall find out the total factors for the number and decide whether the number is a prime or not.

## Find all the factors of a given number

Factors of a given number are the numbers from 1 till the number, for which the number is divisible. It means all these numbers divide the given number and give remainder 0.

Example: The factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24

## Find the nth Power of a given number

The power of a given number obtained by multiplying the number with itself for a specified number of times.

For a given number a, calculate the nth power where n is any number n > 0, a > 0

Example: Func(2, 5) = 5th power of 2 = 32

## Find the factorial of a given number

Factorial of a number n can be termed as multiplication of all numbers from 1 till the number n.

n! = 123*...*n

Example: 5!=12345=120
