Mathematics is the study of numbers. Arithmetic is a vast and a most important branch of mathematics. Most usually, it is concerned with the numbers and various operations on numbers. There are two elementary concepts, known as factors and multiples.
The factors of a number are the list of numbers each of which evenly divides the given number. On the other hand, a multiple of a number is obtained by multiplying that number by another. We shall go ahead in this lesson and learn more about factors and multiples.
