mathlcm

mathlcm is a Python library that provides a function to calculate the least common multiple (LCM) of a list of integers. The LCM is the smallest positive integer that is a multiple of all the numbers in the list. For example, the LCM of 4 and 6 is 12 because 12 is the smallest number that is divisible by both 4 and 6.

The mathlcm library's primary function, also named lcm, takes an iterable of integers as input and returns their least common multiple. It can handle any number of integers provided in the input. The library is designed to be straightforward and easy to use for developers who need to perform LCM calculations in their Python projects.

To use mathlcm, you first need to install it using pip: pip install mathlcm. Once installed, you can import the lcm function and use it as follows: from mathlcm import lcm. Then, you can call lcm with your list of numbers, for instance, result = lcm([4, 6, 8]). The library likely employs efficient algorithms, such as using the relationship between LCM and the greatest common divisor (GCD), to compute the result. The LCM of two numbers a and b can be calculated as (a * b) // gcd(a, b). The mathlcm library extends this concept to handle multiple numbers.
