Books and other education websites provide "matter-of-fact" knowledge. Instead, nubtrek provides a thought-process to discover knowledge.

In each of the topic, the outline of the thought-process, for that topic, is provided for learners and educators.

  • `24`
  • `24`
  • `16`
  • `12`

The answer is "`24`"

Least Common Multiple : The lowest multiple in the common multiples of two or more numbers is the least common multiple (LCM) of those numbers.
