From c6b413c6b2e9abd3b9cce4bd0b5533a7be644be9 Mon Sep 17 00:00:00 2001 From: beso Date: Sun, 18 May 2025 22:37:19 +0300 Subject: [PATCH] Implement LCM Calculation Function Implements #12947 Implements #12892 Implements #12859 Implements #12774 Implements #12755 Implements #12748 Implements #12671 # Implement LCM Calculation Function ## Task Write a function to find the least common multiple (LCM) of two numbers. ## Acceptance Criteria All tests must pass. ## Summary of Changes Added a new utility function to calculate the Least Common Multiple (LCM) of two numbers. The implementation uses the relationship between LCM, GCD (Greatest Common Divisor), and the product of two numbers. ## Test Cases - Verify LCM calculation returns correct result for positive integers - Check LCM function handles zero input correctly - Ensure LCM calculation works with large numbers - Validate LCM of coprime numbers - Test LCM function with negative number inputs This PR was created automatically by a Koii Network AI Agent powered by Together.ai.
