In mathematics, the lowest common denominator or least common denominator (abbreviated LCD) is the least common multiple of the denominators of a set of fractions. It simplifies adding, subtracting, and comparing fractions.

Is the proper term lowest common denominator or least common denominator?

Both!


How are least common multiples and least common denominator realeted?

The same process is used to find both. The only difference is the function of the numbers. When we're talking about fractions, we use the term least common denominator.


What is the lcd of 17 and 34?

I'm not sure if you got the right abbreviation of that term. LCD = Least Common Denominator = 1 GCD = Greatest Common Denominator = 17 LCM = Least Common Multiple = 34


Why do you clear fractions in a linear equation?

Multiply every term in the equation by a common denominator of all the fractions. The least common denominator (if different) will result in smaller numbers that you then have to work with but it is not essential that you use it.


How do you find the greatest common numerator?

That term doesn't exist as a practical matter. Since numbers don't stop, the greatest common numerator is infinite. You might be thinking of the least common denominator.


What term has a numerator and denominator with no common factor?

If the numerator and denominator are prime numbers and not equal then they don't have common factors (except 1 which would be a common factor even if the numerator and denominator were prime numbers).


What does the math term LCD stand for?

LCM is an abbreviation for "least common multiple."


How to you lowest term a fraction?

Divide the numerator and the denominator by their highest common factor.


What is the term used to mean belonging to two or more numbers?

One word would be "common" as in "greatest common factor" or "least common multiple".


What is the lowest common denominator for 9 tenths?

9/10 is already in its lowest term.


Adding dissimilar fractions and whole numbers?

1. change the dissimilar fractions to similar fractions by getting the L.C.D or the least common denominator. 2. add the whole numbers and write down the given denominator. 3. reduce the answer to lowest term if possible.


What is the term LCM?

Least common multiple.


How do you convert slope intercept form to standard form?

y = mx + b, just subtract mx to both sides -mx + y = b. If the slope is a fraction, it is nice to eliminate the denominator first, so go and multiply each term at both sides by the denominator. If both, the slope and the constant, are fractions, multiply each term at both sides by their least common denominator.


What does reduce to the lowest term mean?

It means: Divide numerator and denominator by the same number as many times as you can until they no longer have any common factor except '1'.


What is the term for a fraction when the denominator and numerator do not have any more factors in common?

It is a fraction in its reduced or simplest from.


How do you change higher term to lower term?

When reducing fractions to their lowest terms divide the numerator and denominator by their greatest common factor


How do you reduce the fraction to its lowest term with the greatest common factor?

you only need is to divide the numerator and denominator by your greatest common factor.


How do you cancel a fraction to its lowest term?

If the numerator and denominator have a greatest common factor that is not 1, then it is not completely simplified.


How do you get the lowest term?

When you have a fraction, there is a numerator and a denominator. Also depending on what numbers they are, there is a set of numbers that are that numbers multiples. You have to find the number (must be the same number) that both the numerator and the denominator have in common. Then when you find it, you divide them and that answer will be the lowest term.


Does the term 'mean' mean least in math?

What is the rule for reducing a fraction to its lowest term?

Find the highest common factor (HCF) of the numerator and denominator. If it is 1, then the fraction is already in its lowest term.If not, divide the numerator by the HCF for the new numerator.Divide the denominator by the HCF for the new denominator.The new numerator over the new denominator is the fraction in its lowest terms.


How do you solve equations with variables on both sides with fractions?

You first find a common denominator. The least common denominator is preferable but not essential. Multiply each term in the equation by this common denominator. The equation now has no fractions, only variables on both sides. If the resulting equation is linear, quadratic, cubic or exponential then there are relatively simple ways of solving them. There may be an analytical method for solving polynomials of higher order or other equations. However, whether or not there is a method will depend on the precise nature of the equation.


Lowest common multiple of 120?

To find the least common multiple, you need two terms. For example, the least common multiple of 120 and 5 would be 600 and the least common multiple of 120 and 16 would be 240. With one term, there is no least common multiple.
