The first 5 common multiples are the first 5 multiples of their lowest common multiple (LCM) LCM(9, 10) = 90 → first 5 common multiples are 90, 180, 270, 360, 450.
The first five positive integer multiples of 90 are: 1 x 90 = 90 2 x 90 = 180 3 x 90 = 270 4 x 90 = 360 5 x 90 = 450
The first four are; 4,8,12,16
18, 36, 54, 72, and 90 = the first five multiples of 18
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.
The first four multiples of 20 are: 20 40 60 80
