Functions

func Factorial

func Factorial(input int) int

Factorial returns the factorial(!) of a number (5!=1x2x3x4x5=120) https://www.mathsisfun.com/numbers/factorial.html The formula = n! = n × (n−1)!

func FindFactors

func FindFactors(input int) []int

FindFactors finds the factors of a number. You should be able to do some voodoo with PrimeFactors, but I'm not using that yet.

func FindNumFactors

func FindNumFactors(input int, primes []int) int

FindNumFactors finds the number of factors of a number. You should be able to do some voodoo with PrimeFactors, but I'm not using that yet.

func GetTriangularNumber

func GetTriangularNumber(nth int) int

GetTriangularNumber finds the Nth triangular number. Formule Triangular numbers: https://www.mathsisfun.com/algebra/triangular-numbers.html. Rule: xn = n(n+1)/2

func PrimesBelow

func PrimesBelow(max int) (primes []int)

primesBelow is a primegenerator that finds primes below a number
