They are 9,18,27, and 36.
A general rule for finding if a number is a multiple of 9:
1: Add the digits of the number.
2: Repeat step 1 until you get a single digit.
3a: If the digit is 9, your original number is a multiple of 9.
3b: If the digit is not 9, then your original number is not a multiple of 9.
Examples:
The number is: 223243628
Add the digits: 2+2+3+2+4+3+6+2+8=32
Add the digits: 3+2=5
5≠9
223243628 is not a multiple of 9.
The number is: 27909117983733354999874
Add the digits: 2+7+9+0+9+1+1+7+9+8+3+7+3+3+3+5+4=153
Add the digits: 1+5+3=9
9=9
27909117983733354999874 is a multiple of 9
Answer9, 18, 27,36,45,54,63,72,81,90the first six multiples of 4 are 4,8,12,16,20,24
Common multiples of 7 and 4 include any multiple of 28.
They are: 36, 72, 108.
To find a number that is not a common multiple of 4 and 9, we need to consider the multiples of each number. The multiples of 4 are 4, 8, 12, 16, 20, 24, ... and the multiples of 9 are 9, 18, 27, 36, 45, ... The first number in the list of multiples of 4 that is not a multiple of 9 is 4. Therefore, 4 is a number that is not a common multiple of 4 and 9.
The first two multiples are 9 and 8.
The first 3 multiples of 4 are: 4, 8, and 12.The first 3 multiples of 9 are: 9, 18, and 27.
They are the first three multiples of their lowest common multiple: 36, 72, 108.
lcm(4, 9) = 36 → the two least common multiples (ie the first two common multiples) of 4 and 9 are 36 and 72.
To find the number of 4-digit numbers that are multiples of 9, we first determine the range of 4-digit numbers, which is from 1000 to 9999. Next, we calculate the first and last multiples of 9 within this range, which are 1008 and 9999 respectively. To find the total number of multiples of 9 in this range, we divide the difference between the last and first multiples by 9 and add 1, resulting in (9999 - 1008) / 9 + 1 = 999. Therefore, there are 999 4-digit numbers that are multiples of 9.

180 is the first one.
My thinking is 36,72,108
36, 72.
They are: 36, 72, 108.

Therefore, 4 is a number that is not a common multiple of 4 and 9.
The first three multiples of 3 are 3, 6, 9 The first three multiples of 9 are 9, 18, 27 As the lowest common multiples of 3 and 9 is 9, the common multiples of 3 and 9 are the multiples of 9, thus: The first three common multiples of 3 and 9 are 9, 18, 27
