9,18,27,36,45,54,63,72,81,90,99,108
The answer depends on where the "next" starts from!
18, 36, 54, 72, 90
the next 5 multiples of 7 are: 14,21,28,35,42 and if you don't know the rest they are 49,56,63,70,77 and 84
They are the first three multiples of LCM(5, 9), that is, the first three multiples of 45.
what multiples do 7,5 and 9 have that are the same
The first 5 multiples of 5 are: 5, 10, 15, 20, 25 The first 5 multiples of 9 are: 9, 18, 27, 36, 45 The first 5 multiples of both 5 and 9 are: 45, 90, 135, 180, 225
The first 5 multiples of 9 are 9, 18, 27, 36, and 45. For them to be common, they need to be compared to another set of multiples.
36,45,54
18, 36, 54, 72, 90, 108
The LCM of 5 & 9 is... 45
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.
90. All numbers that are multiples of 3, 5 & 9 are multiples of their lowest common multiple lcm(3, 5, 9) = 45 → multiples of 45 between 49 and 95 is 2 x 45 = 90.
