To find the common multiples of 3, 6, and 18, we need to list out the multiples of each number and find the numbers that appear in all three lists. The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, and so on. The multiples of 6 are 6, 12, 18, 24, 30, and so on. The multiples of 18 are 18, 36, 54, 72, and so on. The first three common multiples of 3, 6, and 18 are 18, 36, and 54.
Factors of 126 are 1, 2, 3, 6, 7, 18, 21, 42, 63, 126 Of those factors, 3, 6, 18, 21, 42, 63, 126 are multiples of 3.
Take the multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, etc. Now, eliminate every fourth number in the sequence (the multiples of 4). The remaining numbers will be multiples of 3, but not of 4.
There are more than four, starting with 12, 15, 18 and 21.
Factors of 21 = 1, 3, 7, 21 Multiples of 21: 21, 42, 63, 84, 105, 126, 147 +21 . . .
18, yes.21, no.
there are infinite amount of common multiples.
Multiples of 6: 12, 18, 24 Multiples of 7: 14, 21, 28
3, 6, 9, 12, 15, 18, and 21 are.
3, 6, 9, 12, 15, 18, 21.
three
All multiples of 72 are greater than 21. If you're looking for factors of 72, use 9 and 12 or 18 and 3
The multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, etc ...The multiples of 6 are: 6, 12, 18, 24, etc ...The multiples of 18 are: 18, 36, 54, etc ...The lowest multiple common to 3, 6, and 18 is 18, so the LCM = 18.
3, 6, 9, 12, 15, 18, 21
Oh, isn't that just a happy little question! When we talk about multiples of 3 and 6, we're looking at numbers that can be divided evenly by either 3 or 6. So, multiples of 3 would be 3, 6, 9, 12, and so on, while multiples of 6 would be 6, 12, 18, 24, and beyond. Just imagine those numbers dancing together in perfect harmony on your canvas!
3, 6, 9, 12, 15, 18, 21 and so on.
6, 12, 18. 7, 14, 21.
