LCM of Two Numbers

The wizards of the Loop Lord academy in the tower of Compilemore have locked the Star Chest. The chest contains the answers to every unsolved problem in the known world, but its seal requires a perfect solution to "LCM of Two Numbers". Apprentice Wizard Elara has been chosen to attempt the unlocking ritual. The tower's stones are old and wise, inscribed with runes of every programming language. Elara's staff crackles with energy as she approaches the chest. The headmaster watches from the shadows, offering neither help nor sympathy.

Read two integers A and B from standard input (space-separated) and print their least common multiple. The ritual can only succeed within these arcane constraints: 1 <= A, B <= 10^6 Elara finds these scroll fragments in the chest's lock mechanism: Input: 4 6 Output: 12 The Star Chest begins to hum. Elara speaks the first words of the incantation. Your code is the rest of the spell. Cast it perfectly, and the secrets of the universe will be hers. Falter, and the chest will remain sealed for another century.

It demands patience, precision, and a deep respect for the boundaries that shape the problem. Many adventurers before you have attempted this trial and failed, their code crashing against the very constraints that the elders inscribed. But you have the tools. You have the training. You have reached the Loop Lord tier, and that alone means the council believes in your potential. Look once more at the examples above. Trace the logic with your finger if you must. Consider the time and memory limits carefully, for they are not suggestions but strict laws of the arena. When you are ready, commit your solution. Let the compiler run. Let the test cases judge your work. If your code is true, the gates will open and you will move closer to the ultimate rank. If not, study the failure, sharpen your algorithm, and try again. For in the halls of CodeTikki, the only thing more important than success is the wisdom gained from the attempt. Remember that the Loop Lord challenge is designed to test not just knowledge, but character. Every edge case is a lesson. Every time limit is a teacher. Every hidden test is a guardian at the gate. Do not rush. Let your code breathe. Let it be as clean as a mountain stream. When the final test passes, you will know that you have earned the title. Until then, code with courage, test with care, and never stop learning.
