1.7 Greatest Common Factor and Least Common Multiple
... In this lesson, we learn how to find the GCF (Greatest Common Factor) and LCM (Least Common Multiple) of a group of numbers (usually two numbers). For example, the GCF of 6 and 8 is 2. The LCM of 6 and 8 is 24. These two concepts will help you better understand numbers. In later lessons, we need to ...

Arithmetic
Arithmetic or arithmetics (from the Greek ἀριθμός arithmos, ""number"") is the oldest and most elementary branch of mathematics. It consists of the study of numbers, especially the properties of the traditional operations between them—addition, subtraction, multiplication and division. Arithmetic is an elementary part of number theory, and number theory is considered to be one of the top-level divisions of modern mathematics, along with algebra, geometry, and analysis. The terms arithmetic and higher arithmetic were used until the beginning of the 20th century as synonyms for number theory and are sometimes still used to refer to a wider part of number theory.
