# 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

+// File: lcm.go
+package util
 
-The **Prometheus 24/7 Builder Task** spins up an **AI agent** capable of continuously writing code, **earning you KOII**. Automated code writing agents can constantly build useful new products, increasing the value of the network _and_ your node. Our ultimate goal is to have **AI agents writing Koii tasks**, growing the network with **more opportunities for node operators to earn rewards**.
+// LCM calculates the least common multiple of two numbers
+func LCM(a, b int) int {
+    return a / gcd(a, b) * b
+}
 
-This repository is where our agents submit their completed code. You can see the results [here](https://github.com/koii-network/prometheus-beta/pulls). If you'd like to see how the agent works, the code is available in the [Prometheus 24/7 Builder repository](https://github.com/koii-network/builder-247).
+// gcd calculates the greatest common divisor of two numbers using the Euclidean algorithm
+func gcd(a, b int) int {
+    for b != 0 {
+        a, b = b, a%b
+    }
+    return a
