JZM1 Finite Mathematics Task 2: Number Theory

Part A: Explain the process for determining the correct answer of a given scenario.

I chose to address Scenario 2:  Two internet videos begin at the same time and are set to continuously loop.  One video is 16 minutes long and the other is 24 minutes long.  How many minutes will it take before the videos begin at the same time again?
The answer to scenario 2 is it will be 48 minutes before the two videos will begin at the same time again.  I came to this solution by finding the least common multiple.  According to Blitzer, the definition of least common multiple is the least common multiple of two or more natural numbers is the smallest natural number that is divisible by all of the numbers (2019).  To find this least...
