    In musical rhythm, the LCD is used in cross-rhythms and polymeters to determine the fewest notes necessary to count time given two or more metric divisions. For example, much African music is recorded in Western notation using 12 8 because each measure is divided by 4 and by 3, the LCD of which is 12.

  3. Least common multiple - Wikipedia

    For example, 10 is a multiple of 5 because 5 × 2 = 10, so 10 is divisible by 5 and 2. Because 10 is the smallest positive integer that is divisible by both 5 and 2, it is the least common multiple of 5 and 2. By the same principle, 10 is the least common multiple of −5 and −2 as well.

    To begin solving, we multiply each side of the equation by the least common denominator of all the fractions contained in the equation. In this case, the least common denominator is () (+). After performing these operations, the fractions are eliminated, and the equation becomes:

    Some LCD panels have native fiber-optic inputs in addition to DVI and HDMI. [156] Many LCD monitors are powered by a 12 V power supply, and if built into a computer can be powered by its 12 V power supply. Can be made with very narrow frame borders, allowing multiple LCD screens to be arrayed side by side to make up what looks like one big screen.

    To write the relation of numerators the second fraction needs another factor of () to convert it to the LCD, giving us + = + (). In general, if a binomial factor is raised to the power of n {\displaystyle n} , then n {\displaystyle n} constants A k {\displaystyle A_{k}} will be needed, each appearing divided by successive powers, ( 1 − 2 x ...

  7. Clearing denominators - Wikipedia

    en.wikipedia.org/wiki/Clearing_denominators

    In mathematics, the method of clearing denominators, also called clearing fractions, is a technique for simplifying an equation equating two expressions that each are a sum of rational expressions – which includes simple fractions.

  8. Greatest common divisor - Wikipedia

    en.wikipedia.org/wiki/Greatest_common_divisor

    The greatest common divisor (GCD) of integers a and b, at least one of which is nonzero, is the greatest positive integer d such that d is a divisor of both a and b; that is, there are integers e and f such that a = de and b = df, and d is the largest such integer.

    en.wikipedia.org/wiki/Talk:Lowest_common_denominator

    The LCD article should deal with the mathematical concept of LCD. The LCD concept is not central to education reform. (If I understand your position re. ER correctly, it seems that you should be interested first of all in a full explanantion of the LCD concept. Inserting the issue of ER only takes away from the explanation of the LCD concept ...
