Well, 99
Both digits are successive counting numbers.
Well, honey, 13 and 9 both go into numbers that are multiples of both 13 and 9. So, the numbers that both 13 and 9 go into are the common multiples of 13 and 9, like 117. Hope that clears things up for you, darling.
The common multiples of 3 and 11 are the infinite set starting 33, 99, 99, 132, 165, 198, 231, 264, 297, 330, and so on. In fact 33n where n is a natural number greater than or equal to 3 will all be common multiples of both numbers.
Oh, what a happy little question! When we talk about multiples, we're looking at numbers that both 2 and 9 can be divided into evenly. The common multiples of 2 and 9 are numbers like 18, 36, 54, and so on - just like little friends skipping along together in the meadow.
The numbers 3, 5, 7, 9, 11, 13, 15, 17, and 19 are not multiples of 2.
3 3 3
Any multiple of 36.
To find the counting numbers less than 200 that are exactly divisible by either 6 or 9, we can use the principle of inclusion-exclusion. The number of multiples of 6 less than 200 is 33 (since 198/6 = 33), and the number of multiples of 9 is 22 (since 198/9 = 22). The multiples of both 6 and 9 (which is 18) less than 200 is 11 (since 198/18 = 11). Thus, the total is 33 + 22 - 11 = 44. Therefore, there are 44 counting numbers less than 200 that are divisible by either 6 or 9.
The common multiples of any two (or more) numbers are multiples of their lowest common multiple (lcm). lcm(9, 11) = 99 → first five common multiples are: 99, 198, 297, 396, 495

Well, honey, let me break it down for you. No, not all multiples of 9 are multiples of 6. See, multiples of 9 are numbers like 9, 18, 27, and so on, while multiples of 6 are numbers like 6, 12, 18, and so forth. So, while 18 is both a multiple of 9 and 6, not all multiples of 9 will be multiples of 6. Hope that clears things up for ya!
Yes. Both 9 and 11 are prime numbers.
