# Euclidean algorithm - Flowchart

"In mathematics, the Euclidean algorithm, or Euclid's algorithm, is a method for computing the greatest common divisor (GCD) of two (usually positive) integers, also known as the greatest common factor (GCF) or highest common factor (HCF). ...
The GCD of two positive integers is the largest integer that divides both of them without leaving a remainder (the GCD of two integers in general is defined in a more subtle way).
In its simplest form, Euclid's algorithm starts with a pair of positive integers, and forms a new pair that consists of the smaller number and the difference between the larger and smaller numbers. The process repeats until the numbers in the pair are equal. That number then is the greatest common divisor of the original pair of integers.
The main principle is that the GCD does not change if the smaller number is subtracted from the larger number. ... Since the larger of the two numbers is reduced, repeating this process gives successively smaller numbers, so this repetition will necessarily stop sooner or later - when the numbers are equal (if the process is attempted once more, one of the numbers will become 0)." [Euclidean algorithm. Wikipedia]
The flowchart example "Euclidean algorithm" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Mathematics solution from the Science and Education area of ConceptDraw Solution Park.

## How to Create a Timeline Diagram in ConceptDraw PRO

A Timeline is a chart which displays a project plan schedule in chronological order. A Timeline is used in project management to depict project milestones and visualize project phases, and show project progress. The graphic form of a timeline makes it easy to understand critical project milestones, such as the progress of a project schedule. Timelines are particularly useful for project scheduling or project management when accompanied with a Gantt chart. It captures the main of what the project will accomplish and how it will be done. making a project timeline is one of the most important skills a project manager needs have. Making comprehensive, accurate timelines allows you getting every project off in the best way. ConceptDraw PRO allows you to draw a timeline charts using special library.

## How to Track Your Project Plan vs. the Actual Project Condition

Conceptdraw PROJECT allows to follow how the project is going. You can easily compare the actual project data with the planned ones. The best tool for effective tracking of the project execution is to compoare real data with project baseline. It consists from the baseline start, baseline finish and baseline cost. Along with Baseline tracking ConceptDraw PROJECT offers several types of visual reports that can help to assess visually the difference between planned and actual project data.

## How to Use the Effort-Driven Scheduling Method

The idea of Effort-driven scheduling in project management is that each project task can be scheduled and assumed basing to the amount of the available work hours. Effort-driven scheduling is used as the default method of project scheduling in ConceptDraw PROJECT. This means that task duration, units, and work amount for individual assignment depends on the entire work, required for a given task. Whether you add or remove resources, the total work amount still the same, while ConceptDraw PROJECT regulates the duration of task or units assigned for the given resources.

## How to Create a Bank ATM Use Case Diagram

UML diagrams are often used in banking management for documenting a banking system. In particular, the interaction of bank customers with an automated teller machine (ATM) can be represented in a Use Case diagram. Before the software code for an ATM, or any other system design, is written, it is necessary to create a visual representation of any object-oriented processes. This is done most effectively by creating a Unified Modeling Language (UML) diagram, using object-oriented modeling. UML works as a general purpose modeling language for software engineers or system analysts, offering a number of different diagram styles with which to visually depict all aspects of a software system.
ConceptDraw PRO diagramming software, enhanced and expanded with the ATM UML Diagrams solution, offers the full range of icons, templates and design elements needed to faithfully represent ATM and banking information system architecture using UML standards. The ATM UML Diagrams solution is useful for beginner and advanced users alike. More experienced users will appreciate a full range of vector stencil libraries and ConceptDraw PRO's powerful software, that allows you to create your ATM UML diagram in a matter of moments.
