-- The lowest common multiple of 18 and 15 is 90.
-- When you ask for the "lowest", then one of them is all you're going to get.
If I gave you two different ones and told you that they're both the 'lowest',
then you'd want to know which lowest is lower than the other lowest.
There is an infinite number of common multiples for 9 15 and 18. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple (LCM) of 9 15 and 18 is 90.
The lowest common multiple is 18. The first four common multiples are thus the first four multiples of 18 and are: 18, 36, 54 and 72.
lowest common multiple is 18
All multiples of 90.
18, 36, 54
The multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, etc ...The multiples of 6 are: 6, 12, 18, 24, etc ...The multiples of 18 are: 18, 36, 54, etc ...The lowest multiple common to 3, 6, and 18 is 18, so the LCM = 18.
