Just 72. It was found by multiplying 8 and 9. --------------------------------------- The common multiples of two numbers are the multiples of their lowest common multiple. LCM(8, 9) = 72 The common multiples of 8 and 9 are 72, 144, 216, ... The only common multiples less than 100 are 72 only.
the common multiples between 1 and 100 for 9 and 10 are just 90!

9,18,27,36,45,54,63,72,81,90,99
90 that is all
Just 90.

I don't know about "magic" in this context. Multiples are the number 9, multiplied by an integer, for example: 0 x 9 = 0 1 x 9 = 9 2 x 9 = 18 etc. If you just keep adding 9 at a time, you will get all the multiples.
Just 72.
9,18,27,36,45,54,63,72,81,90,99
100 of them.
11
Common multiples of 9 and 10 are all of the multiples of 90.
Yes, all multiples of 9 are also multiples of 3.but they're not all of them. Every multiple of 9 is also a multiple of 3, but there are more multiples of 3 besides those.
9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99
