You could A: list out multiples of the denominators until you find one that is in each list. Example: 1/2, 1/3, 1/4
2, 4, 6, 8, 10, 12
3, 6, 9, 12
4, 8, 12
12 is in each list, therefore it is the least common denominator. You could also B: Find the prime factorization, or finding it's factorization in prime numbers. It is achieved like this:
1/2, 1/3, 1/4
2: 2
3: 3
4: 2*2
You then multiply all of the numbers together, like so:
2*3*2*2= 24
HOWEVER: If there are two numbers in the same column
(2
3
2)
like the twos, you take one of them out, leaving you with 2*3*2 which equals 12. Either of these ways work, and they get the same answer every time.

What is the GCF of 3x squared plus 2x - 5?
3x2 has x, x2 , and 3 as factors. 2x-5 does not have any of those as factors. So the greatest common factor is 1. If you were adding rational expressions with those two expressions in the denominator, you would need to multiply them together to find the least common denominator.
If you are adding or subtracting rational expressions with different polynomial expressions in the denominator explain how you would find the LCD.?
One way is to simply multiply the denominators together. That won't give you the LEAST common denominator, but it will give you A common denominator.You can also use one of the several methods explained in the Wikipedia article on "Least common multiple". For example, you can split each number up into prime factors, and multiply all the unique prime factors together. If a prime factor appears more than once in some of the numbers, use the highest power.
What is the least common denominator of 12 and 5?
The least common denominator is 60.
How is the least common denominator different from least common multiple?
a least common (LCD) denominator is a least common multiple (LCM); only it's a fraction and it's LCM is in the denominator's place.
What is a common denominator between 4 and 10?
A common denominator, though not the least, is 40.

What is the smallest common multiples is called?
It is usually called the least common multiple. But it can also be called the least/lowest common denominator when it is used for addition or subtraction of rational fractions.
What is the LCM of the denominators of two or more fractions?
The least common multiple of two or more denominators is known as the least common denominator, or LCD.
What is the least common denominator of two fractions?
The least common denominator is the least common multiple of the denominators of the fractions.
What is the least common denominator of 42 and 58?
The least common denominator is 1. The greatest common denominator is 2. The least common multiple is 1,218.
What is the least common denominator for12and15?
The least common denominator (LCD) is 1.
What is the least common denominator of 3 and x?
The least common denominator is 3x.
What is the least common denominator of 12 and 5?
The least common denominator is 60.
What are the steps in solving rational equations?
1. First we need to determine the least common denominator of the fractions in the given rational equation. 2. We need to take out the fractions by multiplying All terms by the least common denominator. 3. Then we have to simplify the terms in rational equation. 4. Solve the resulting equation. 5. Check the answers to make confident the solution does not make the fraction undefined.
