kgV {cycloids}

Calculates the least common multiple of two natural numbers a and b

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

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.
