Example: 1/30 and 1/42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCD
What do you mean "take out"? To find the LCD for several fractions look only at the denominators and find the lowest number or algebraic expression that evenly divides into all of them.

IS THE LCD OF TWO FRACTIONS THE SAME AS THE LCM NUMERATORS AND FRACTIONS?
The LCD of two fractions is the same as the LCM of their denominators.
What are the rules of the dissimilar fractions?
I assume you mean, with different denominators. If you want to add the fractions, subtract them, or compare them (determine which one is greater), you have to convert them to similar fractions (fractions with the same denominator) first. Converting to similar fractions is not necessary, and usually doesn't even help, if you want to multiply or divide fractions.
What the difference between like and unlike fraction?
fractions having same denominators are like fractions & others are unlike fractions
Do you need to find the LCD in multipliying?
When multiplying fractions, it is not necessary to find the LCD first.
Comparing fractions without using an lcd?
It is easy: just convert to decimal fractions.
What is a dissimilar fractions?
Dissimilar fractions are fractions that have different denominators.
Adding dissimilar fractions?
In adding dissimilar fractions first you have to find the LCD! -> LCD means Least Common Denominator. *For example 2/3 3 6 9 12 + 3/4 4 8 12 the LCD is 12 put 12 under the - divide 12 to denominator and write the answer in left of given question
Is dissimilar fractions can be discovered as proper fraction?
Dissimilar fractions may or may not be proper fractions.
What is disimiliar fraction?
Dissimilar fractions have different denominators.
How do you rename dissimilar fractions to similar fractions?
2/3,3/8Find the LCD. The LCD of 3 and 8 is 24. Multiply the fractions by whatever it takes to make 24.2/3 x 8/8 = 16/243/8 x 3/3 = 9/24
Butterfly Method?
Used for adding dissimilar fractions
What is the meaning of dissimilar fraction?
The meaning of dissimilar fractions is when there is a pair or more of fractions that don't have the same denominator.
How do you compare fractions in terms of similar and dissimilar fractions?
You can compare similar fractions by looking at their numerators. You can compare dissimilar fractions by converting them to similar fractions and looking at their numerators. You can convert a dissimilar fraction to a similar fraction by finding the least common denominator.
What are Dissimilar Fractions?
Dissimilar fractions are fractions whose denominators are not the same. for example 3/8 and 1/2, their denominators are 8 and 2.
What is the meaning dissimilar fraction?
They are fractions that have different denominators as for instance 3/4 and 5/8 are dissimilar fractions.
What is a name for fractions with different common denominators?
Dissimilar fractions.
How do you add and subtract dissimilar fraction in simple and mixed formed?
In adding or subtracting dissimilar fractions, you will need first to get its LCD or least common denominator. For example: 3/2 + 5/3 = ? We will get the LCD of two and three and we will get 6 So the equation will become: 9/6 + 10/6 Then the final answer will be : 19/6
