Lowest Common Denominator

A divisor of an integer divides that integer without leaving a remainder. The divisors of 28 are 1, 2, 4, 7, 14, and 28. The divisors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.

A common divisor of two integers divides both without leaving a remainder. The common divisors of 28 and 60 are 1, 2, and 4.

The greatest common divisor of two integers is the common divisor that is greater than all of the other common divisors. The greatest common divisor of 28 and 60 is 4.

The concept of a least common divisor is meaningless, as it is always 1.

A fraction, such as 5/8 and 3/10, consists of a numerator and a denominator. Any integer can be a numerator. Any non-zero integer can be a denominator.

“Lower” and “lowest” compare altitudes, not magnitudes.

Anyone using the phrase Lowest Common Denominator reduces the Greatest Common Divisor of human knowledge.
