A multiple of a number is the product of that number and an integer. 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.
Here, 36 is the least common multiple of 12 and 18. Their product, 216, is also a common denominator, but calculating with that denominator involves larger numbers:
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.
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.

Equivalently, g(n) is the largest least common multiple (lcm) of any partition of n, or the maximum number of times a permutation of n elements can be recursively applied to itself before it returns to its starting sequence. For instance, 5 = 2 + 3 and lcm(2,3) = 6. No other partition of 5 yields a bigger lcm, so g(5) = 6.
Mathematics: 2,520 (5×7×8×9 or 2 3 ×3 2 ×5×7) is the least common multiple of every positive integer under (and including) 10. Terrorism: 2,996 persons (including 19 terrorists) died in the terrorist attacks of September 11, 2001. Biology: the DNA of the simplest viruses has 3,000 base pairs. [11]
