You can find a common denominator by multiplying the denominators together. You can find the least common denominator by finding their LCM.
Example: 1/30 and 1/42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the highest amount of each factor.
2 x 3 x 5 x 7 = 210, the LCD

Simplest form
What is seven eighths plus seven eighths?
1 and 3/4To add two fractions, combine the numerators when there is a common demominator (then you can also simplify).In the question 7/8 + 7/8 ... there is a common denominator.So you get 14/8This can be simplified to 7/4This can be simplified to 1 and 3/41 and 3/4 is your answer (which is 1.75 in decimal form).
What are the numerator and demominator relationships of one tenth?
The denominator is ten times the value of the numerator.
What is the right common denominator for 5 over 6 minus 4 over 9?
There can be several common denominators for calculations like this. The product of the two here will work (6x9) as will any integer multiple of that. People generally look for the LOWEST common denominator and that is found by looking at the factors involved. 6 is 3x2 and 9 is 3x3, so when you have covered the two 3s from the 9, you don't need any more to deal with the 3 in the 6, but you do need a 2. So the lowest common demominator is 2x3x3, or 18.

How do you find the most common multiple?
There is no "most common multiple". To find all common multiples, you start by finding the least common multiple. All other common multiples are multiples of this least common multiple.
