Define Least Common Denominator

In the previous post we have discussed about What are Rational numbers

and In today's session we are going to discuss about Least Common Denominator,  We all generally deal with the addition and the subtraction of two or more fractions while studying the basic math and the primary step which we have to perform to carry out such types of the additions and the subtractions of the different fractions is to find out the least common denominator of the two or more number of the fractions. So in this article we will study about the least common denominator and we will also see the method to calculate it. The lowest common denominator is generally denoted by LCD in the context of the math.

So first let us start with the definition of the least common denominator. The lowest common denominator in the theory of the basic mathematics can be called as the common multiple which is the smallest, of two or more number of the denominators when considered for any of the set or the group of the fractions. We can also modulate our definition of the lowest common denominator in another way and say that it is the smallest of those types of the integers which are positive and which are denoting the different multiples of any number of the denominators of the fractions.

Now let us take some of the simple examples to understand the concept of the lowest common denominator more precisely. Suppose we have to calculate the lowest common denominator of the two fractions 7/9 and 4/13. So the maximum of the common factors of the 2 denominators 13 and 9 is 1 only. So after multiplying 13 and 9 we obtain 117 and then we divide it by 1 to obtain 117 as the lowest common denominator.
