I presume you mean what are all the multiples of 9 up to 100 (and not what are all the multiples of 9, 10, 11, ..., 100 of which there are infinitely many): 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.
All multiples of 3 have digits that add up to a multiple of 3. There are 333 multiples of 3 between 1 and 1000.

That the sum of its digits add up to 9 as for example 9*9 = 81 and 8+1 = 9
Multiples of 25 up to 1000 are: 25;50;75;100;125;150;175;200;225;250;275;300;325;350;375;400;425;450;475; 500;525;550;575;600;625;650;675;700;725;750;775;800;825;850;875;900;925;950;975;1000
All of its multiples from 3 to 999
All multiples of 12, such as 120, 600, 660.

Oh, what a happy little question! Multiples of 27 include 27, 54, 81, and so on. Multiples of 9 include 9, 18, 27, and more. Multiples of 15 are 15, 30, 45, and beyond. And multiples of 81 include 81, 162, 243, and many more. Just remember, each number has its own special multiples waiting to be discovered!
250
16, 81, 256, 625 all have five factors.
All multiples of 3 have digits that add up to a multiple of 3. There are 333 multiples of 3 between 1 and 1000.
72, 81, 90
To find all the multiples of 30 up to 1000, we can start by dividing 1000 by 30, which equals 33 with a remainder of 10. This means the last multiple of 30 within 1000 is 990. So, the multiples of 30 up to 1000 are 30, 60, 90, 120, all the way up to 990.
27, 54, 81, 108, 136, 162, 189, 216
There are 143 such numbers, too many to list.
