The answer depends on if 4 and 9 WHAT!
lcm(4, 9) = 36 → the two least common multiples (ie the first two common multiples) of 4 and 9 are 36 and 72.
The first 3 multiples of 4 are: 4, 8, and 12.The first 3 multiples of 9 are: 9, 18, and 27.
It is: 36
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 common multiples of 4 and 9 are 36, 72, 108 and so on.
The multiples of 36 go on forever.

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.
The LCM of 4, 9, and 12 is 36
4 and 8 are multiples of 2. 6 and 9 are multiples of 3. 40 and 50 are multiples of 10.
There are 5 multiples of 9. There are 4 multiples of 12. There is 1 number that is a multiple of both, 36.
