20,40,60
Proof
(20)(20/4=5)(20/5=4)(20/10=2)
And
(40)(40/4=10)(40/5=8)(40/10=4)
And
(60)(60/4=15)(60/5=12)(60/10=6)
the first three multiples of 3 and 11 is 33,66,and 99.
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
They are the first three multiples of their lowest common multiple: 36, 72, 108.
lcm(2, 7) = 14 → first 3 common multiples are: 14, 28, 42; lcm(2, 8) = 8 → first 3 common multiples are: 8, 16, 24; lcm(7, 8) = 56 → first 3 common multiples are: 56, 112, 168; lcm(2, 7, 8) = 56 → first 3 common multiples are: 56, 112, 168.
The first 10 multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, and 30.

Because 9 is a multiple of 3, the common multiples of 3 and 9 are the multiples of 9. The first 10 common multiples of 3 and 9 are 9, 18, 27, 36, 45, 54, 63, 72, 81, and 90.
30, 60, 90
They are 30, 60 and 90.
