Formula:
The Lowest Common Denominator (LCD) is the smallest positive integer that is a multiple of two or more denominators. It is essentially the Least Common Multiple (LCM) of the denominators.
For two numbers, a and b, the relationship between LCM and the Greatest Common Divisor (GCD) is:
LCM(a, b) = (|a × b|) / GCD(a, b)
For multiple numbers, the LCM is found iteratively: LCM(a, b, c) = LCM(LCM(a, b), c).
