The sum of the digits in each multiple is 9 .
It also works just fine for ' 1 '.
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.
There are 5 multiples of 9. There are 4 multiples of 12. There is 1 number that is a multiple of both, 36.
They are multiples of 1, 3, and 9.
1, 9, and 81 are the only multiples of 81
9,18,27,36,45,54,63,72,81,90,99
Infinitely many.
The multiples of 9 are: 1 and 9 3 and 3

Both digits are successive counting numbers.
To find the multiples of 9 up to 9000, you can use the formula: (9 \times n), where (n) is a positive integer. The first few multiples of 9 are 9, 18, 27, 36, and so on. To find the multiples of 9 up to 9000, divide 9000 by 9, which equals 1000. Therefore, the multiples of 9 up to 9000 are all the multiples of 9 from 9 to 9000, inclusive.
Oh, what a happy little question! To find how many 4-digit numbers are multiples of 9, we need to see how many multiples of 9 fall between 1000 and 9999. To do this, we divide the range's endpoints by 9 and subtract the whole numbers in between. By doing this gentle math, we can find the number of delightful 4-digit numbers that are multiples of 9.
1, 3 and 9 are common factors of 27, 45 and 81. 27, 45 and 81 are multiples of 1, 3 and 9.
There are 5 multiples of 9. There are 4 multiples of 12. There is 1 number that is a multiple of both, 36.
They are multiples of 1, 3, and 9.
Multiples are just numbers that can be multiplied together to find the given number. So: Multiples of 9: 1,3,9 Multiples of 18: 1,2,3,6,9,18 Common Multiples of 9 & 18: 1,3,9
To find the LCM of a number in this case 6 and 9 you find all of their multiples that they share in this caseThe multiples of 6 are 2,3,6
The factors of 9 are 1, 3, and 9. The multiples of 9 are 9, 18, 27, 36, 45,...etc.
