Least Common
Multiple (LCM)
The least common multiple is the
smallest number that two (or more) given numbers both
divide into.
Examples: The
LCM of
6 and
9 is 18.
The LCM of
4 and
5 is 20.
The LCM of
2 and
10 is 10.
A common way to write it is
LCM (

When used during fraction problems, another name
for the least common multiple is the "least common
denominator" (LCD). |
