Understanding the LCM
The Least Common Multiple (LCM) of two or more integers is the smallest positive integer that is divisible by each of the integers.
Formula using GCD
The LCM can be efficiently calculated using the Greatest Common Divisor (GCD). For two integers 'a' and 'b', the formula is:
\[ \text{lcm}(a, b) = \frac{|a \cdot b|}{\text{gcd}(a, b)} \]
To find the LCM of a list of numbers, you find the LCM of the first two, then the LCM of that result and the next number, and so on.
Enter numbers separated by commas or spaces.
