Factorial

Description

Factorial helps you to calculate the factorial of a number or a list of numbers. e.g factorial of 5 = 120. It has also the features to find the greatest common factor (GCF) of the series of numbers and the least common factor (LCM).

Requirements

• Ruby(tested with 1.9.3)
• Rspec(only if you want to run the tests)

Installation

gem install factorial

Usage

require 'factorial'

For determining the factorial of a number

result = Factorial::Base.new(numbers) e.g 2, 5

result.factorial_result => 2, 120

For determining the GCF

result.gcf_result => 1

For determining the LCM

result.lcm_result => 10
