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

The process for subtracting fractions is, in essence, the same as that of adding them: find a common denominator, and change each fraction to an equivalent fraction with the chosen common denominator. The resulting fraction will have that denominator, and its numerator will be the result of subtracting the numerators of the original fractions.
The lowest common divisor is a term often mistakenly used to refer to: Lowest common denominator , the lowest common multiple of the denominators of a set of fractions Greatest common divisor , the largest positive integer that divides each of the integers
David Lever, 55, was charged with three counts of murder in the killings Friday of Anthony “Tony” Gribble, 80; Paula Gribble, 76; and Enrique Reyes, 64, according to the sheriff's office.
The smallest common multiple of the two denominators 6 and 15z is 30z, so one multiplies both sides by 30z: 5 x z + 2 y = 30 z . {\displaystyle 5xz+2y=30z.\,} The result is an equation with no fractions.
