Least Common Multiple & Decreasing Order - Practice Problem | CAVEMAN CHANG

For this video series, I will focus on practice problems. Each and every one of these questions, I selected because I feel they truly highlight certain math concepts or they may show up in a standardized test. In order to best use this video, I recommend you pause the video and try to solve the problem before unpausing to see the solution and explanation.

Problem of the Video: List in decreasing order 4/9, 7/15, 5/12

Please note that there may be some confusion depending on the wording on the question. The problem could be asking for sum of unique prime factors or sum of all prime factors.

There are many ways to solve a math problem so please share in the comments if you solved this problem differently.
