2, 4, 6, 8, 10, 12.
60, 120, 180 and so on.
Multiples of 90
12 and all its multiples.
It is 12 and its multiples.
10 is.
Look at the multiples of 6. The smallest and greatest multiples of 6 that can be divided evenly by 4 are 12 and 48. So the common multiples of 4 and 6 up to 50 are 12, 24, 36, and 48.
The multiples of 10 are: 1, 2, 5, 10 The multiples of 5 are: 1 and 5. The multiples of 6 are: 1, 2, 3, and 6. The multiples of 8 are: 1, 2, 4, and 8. The number that they all have in common is 1, so the lcd is one.
The numbers: 0, 12, 24, 36, 48, etc. (the multiples of 12) are the only common multiples of 4 and 6.
