LCM Calculator v1

The Last API Ever, to find the LCM of a range of numbers

drawing

About Application

Finds the smallest number that can be divided by a sequential set of numbers from 1 till a given range

Example: 1,2,3,4,5 = 60

60 is the smallest number that can be divided by each of the numbers from 1 to 5 without any remainder.

This program is intended to extend another application. For instance as (micro)service to your existing product

Usage

#Instructions:
Perform a GET-request to path: localhost:8080/LeastCommonMultipleTill, proceeded with a query parameter: till
Tip: Use an http client like Postman to test the requests.

      Example:

localhost:8080/LeastCommonMultiple?till=13

      The API will return a string containing:

360360 is the smallest number that can be divided by each of the numbers from 1 to 13 without any remainder.

      Notes & Limits:

  • Inserting value other than number will return statuscode of 400 - BAD Request
  • Note that its not possible to request a maximum range greater then 42
  • Results of this application are tested based on the standards of Calculator.net

Run Project

Prerequisites: Maven is installed on the machine & the project is unzipped.

  1. Navigate to the projects root directory /West - Assignment. (See that the pom.xml is located here)

  2. Run command: mvn spring-boot:run

    • To skip tests run: mvn -DskipTests spring-boot:run
    • To quit application run: ctrl + c, Terminate Batch Job(Y/N)?: N (Kill in task manager if necessary)

  3. Follow usage instructions

Install Prerequisites

Prerequisites: Maven is installed on the machine & the project is unzipped.

1. Install Project:

      Direct install of Project github.com/1eam/Least_Common_Multiple_Calculator/archive/refs/heads/master.zip

2. Install maven:

      https://dlcdn.apache.org/maven/maven-3/3.8.3/binaries/apache-maven-3.8.3-bin.zip [Download of 03-11-21]

3.2 Test successful installation of maven:

      run: mvn -v response should look like:

Run Maven Test

Install reference: https://maven.apache.org/install.html#

Considered Updates:

  • Ability to calculate LCM of range x till x. Example: 3 - 45, 13 - 17, 19 - 23
  • Ability to calculate LCM of x numbers. Where x are multiple random numbers. Example 23, 4, 15 and 8 = 2760
