The lowest common denominator is simply the lowest real number that two separate denominators can be converted to. Fractions are easier to add, subtract, and compare when they are in terms of the same denominator.
For example, we will use the numbers 1/3 and 1/4. First find the lowest common multiples (LCM).
3:3,6,9,12
4:4,8,12
Now that you have found the lowest common multiple, you find an equivalent fraction that has the same value.
1/3 * 4/4 = 4/12
1/4 * 3/3 = 3/12
When you multiply the denominator by a number, you have to do the same for the numerator. This is called the Property of One. Now you add the two fractions together.
4/12 + 3/12 = 7/12
Find the lowest common multiple of the denominators and adjust the fractions accordingly
Addition or subtraction of fractions require "like" fractions: that is, fractions with the same denominator.
When adding or subtracting fractions first make sure that the denominators are the same if they aren't then find the lowest common denominator and alter the fractions accordingly
If the fractions do not all have the same denominator, find a common multiple of the denominators (ideally the lowest common multiple) and convert the fractions to equivalent fractions with this denominator. Now with all the fractions with the same denominator, add together the numerators. Finally, reduce the fraction to simplest terms, converting any improper fraction to a mixed number.

Denominator
When adding or subtracting fractions with different denominators, the first step is to find a common denominator. This involves finding the least common multiple (LCM) of the two denominators. Once you have a common denominator, you can then add or subtract the numerators of the fractions accordingly.
First find the lowest common denominator and then adjust the fractions accordingly before subtracting the numerators
find the lowest common denominator
There isn't a universal answer to all problems. What you should try to do is find the lowest common denominator between the fractions you are adding.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
Yes that is the most effective approach in reducing fractions and finding their lowest common denominator.
Find the lowest common denominator
Find the lowest common denominator, convert them, and arrange them in ascending order.
The first step is to find the lowest common denominator of the fractions.
There doesn't appear to be any fractions there but to find the LCD of fractions is done in the same way as finding the lowest common multiple of numbers.
