4, 8, 12, 16, 20, 24, 28, 32, 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.
9,18
There are an infinite number of multiples of any number. Therefore, it is impossible to list all the multiples of 3 and 4. A list of the first 10 multiples: Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40
18, 36, 54, 72, 90, 108
9
9,18,27,36,45,54,63,72,81,90,99,108
9, 18, 27.
Itself and any multiples of 9
Well, honey, to find the number of 4-digit multiples of 9, you just need to divide the largest 4-digit multiple of 9 (9999) by 9 and subtract the smallest 4-digit multiple of 9 (1008) divided by 9. So, 9999 ÷ 9 - 1008 ÷ 9 = 1111 - 112 = 999. That's right, there are 999 4-digit numbers that are multiples of 9.
The answer depends on if 4 and 9 WHAT!
36,45,54
That's an infinite list.
