The word "lowest" is a superlative. What that means is that there can only be one such number. Therefore, the question should be what is, not what are.
The lowest [common] multiple of 4, 6 and 9 is 36.
The least common multiple of 9 , 4 , 6 = 3
The lowest multiple of 6 and 9 is 18, since it is the smallest number that is divisible by both 6 and 9.

The lowest common multiple of 2, 6, and 9 is 18.
It is 72
The least common multiple of 9 , 4 , 6 = 3
It is 3636
The lowest multiple of 6 and 9 is 18, since it is the smallest number that is divisible by both 6 and 9.
LCM(2, 3, 4, 6, 8, 9, 10) = 360
Because 36 is the lowest number that can be divided by ALL THREE numbers (lowest common multiple).
