A volcanologist is studying two volcanic sites. Site A has an eruption frequency of every 4 years, and Site B erupts every 6 years. If both sites erupted this year, in how many years will both sites erupt simultaneously again?

Understanding Volcanic Eruption Cycles: When Will Sites A and B Erupt Together Again? Volcanologists are constantly analyzing eruption patterns to predict future activity and understand the underlying geological forces driving volcanic behavior. A fascinating question arises when studying two key volcanic sites—Site A and Site B—whose eruption cycles offer clear insights into natural periodicity. Recently, a volcanologist focused their research on two active sites: Site A erupts every 4 years, and Site B erupts every 6 years. What’s intriguing is that both sites erupted together this year. Scientists seek to determine the next year when both will erupt simultaneously, revealing important patterns in Earth’s dynamic processes. ### Discovering the Least Common Multiple (LCM)
