kgV: Calculates the least common multiple of two natural numbers a... In cycloids: cycloids

Description

The function kgV calculates the least common multiple of two natural numbers. In this package it is used by the function `zykloid` and by the function `npeaks` which calculates the number of peaks (or loops) a cycloid has. As it might be useful for other purposes, it is externally available in this package.

Usage

 `1` ```kgV(a, b) ```

Arguments

 `a` A natural number (integer value > 0) `b` A natural number (integer value > 0)

Value

A natural number if a and b are natural numbers. In any other case, the function returns NA.
