The denominator is the bottom number in a fraction. If you had two fractions, and were asked to figure out the least common denominator, you'd have to find the smallest number both of the denominators go into.
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.
I am guessing you mean the least common denominator, which is the LCM of the denominators 4 and 20. The answer is 20.
LCM is an abbreviation for "least common multiple."
I think it means Least Common Multiple...
if you mean for 1/3 and 1/12, then to find common denominators, you just list multiples of the denominators 3 and 12. for 3 :3, 6, 9, 12... for 12:12, 24, 36... 12 is the smallest number in both lists, so it is the least common denominator.
The least common multiple, or LCM, is the smallest number that all the members of a given set of numbers will divide into evenly with no remainder.
In a math problem, least means smallest.
It means find the LCM of the denominators. In order to add and subtract fractions with unlike denominators, it is necessary to convert them to equivalent fractions with a common denominator. Example: 1/4 + 1/6 The LCM of 4 and 6 is 12. 1/4 = 3/12 1/6 = 2/12
the average
No, it means average.
Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.
I'm not sure what you mean by lowest common factor, typically math teacher will ask for least common multiple or greatest common factor on your homework.While the lowest common factor is 1, 1 is also the greatest common factor. The least common multiple is 640.
