EXAMPLE 1
Using the Least Common Multiple
You can find when the model trains described
above will return to the station at the same time
by finding the least common multiple of 4 and 6.
Begin by writing the multiples of 4 and 6. Then
identify any common multiples.
12, 24, and 36 are common multiples, so the LCM
is 12.
Multiples of 4 4, 8, 12, 16, 20, 24, 28, 32, 36,
. . .
Multiples of 6 6, 12, 18, 24, 30, 36, . . .
