    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

    en.wikipedia.org/wiki/Least_common_multiple

    The least common multiple of the denominators of two fractions is the "lowest common denominator" (lcd), and can be used for adding, subtracting or comparing the fractions. The least common multiple of more than two integers a , b , c , . . . , usually denoted by lcm( a , b , c , . . .) , is defined as the smallest positive integer that is ...

    r N−3 = r N−5 − q N−3 r N−4. Substituting these formulae for r N −2 and r N −3 into the first equation yields g as a linear sum of the remainders r N −4 and r N −5 . The process of substituting remainders by formulae involving their predecessors can be continued until the original numbers a and b are reached:

    The least common denominator is when you use one of the denominators you are adding, the answer should be correct, the greatest common denominator, is not correct, and the greater it is, the further away it is from the truth, unless you take two further actions to correct the problem.

  8. Modulo - Wikipedia

    en.wikipedia.org/wiki/Modulo

    In computing, the modulo operation returns the remainder or signed remainder of a division, after one number is divided by another, called the modulus of the operation.. Given two positive numbers a and n, a modulo n (often abbreviated as a mod n) is the remainder of the Euclidean division of a by n, where a is the dividend and n is the divisor.

  9. Cross-multiplication - Wikipedia

    In mathematics, specifically in elementary arithmetic and elementary algebra, given an equation between two fractions or rational expressions, one can cross-multiply to simplify the equation or determine the value of a variable.
