First, factor:
16 = 2*2*2*2
18 = 2*3*3
Multiply the factors (only count overlapping ones once) to find the least common multiple (LCM)
LCM = 2*2*2*2*3*3 = 144
The multiples of 16 and 18 are {144, 288, 432, 576...}
All multiples of 16 are also multiples of 2.
Some of the multiples of 14 are the same as the multiples of 16, but not all of them.
All multiples of 36 are multiples of 18.
Multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and so on. Multiples of 6 are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, and so on.
The multiples of 18 in ascending order are 12345678
