Example of the least common multiple
This example shows how to calculate the least common multiple of the integers 18 and 30.
Multiples of 18 and 30 are:
\(V_{18} = \{18, 36, 54, 72, 90, 108, 126, 144, 162, 180, \dots\} \)
\(V_{30} = \{30, 60, 90, 120, 150, 180, 210, 240, \dots\} \)
The common multiples are marked.
\(V_{18} = \{18, 36, 54, 72, \underline{90}, 108, 126, 144, 162, \underline{180}, \dots\} \)
\(V_{30} = \{30, 60, \underline{90}, 120, 150, \underline{180}, 210, 240, \dots\} \)
Find and mark the least common multiple
\(V_{18} = \{18, 36, 54, 72, \color{blue}{\underline{90}}, 108, 126, 144, 162, \underline{180}, \dots\} \)
\(V_{30} = \{30, 60, \color{blue}{\underline{90}}, 120, 150, \underline{180}, 210, 240, \dots\} \)
