They are all even and multiples of 12, which is the lowest common multiple of 3 and 4.
Multiples of 3: 3 6 9 12 15 18Multiples of 4: 4 8 12 16The lowest multiple that is common to both 3 and 4 is 12.
To find the least common denominator, list the multiples of each denominator. The lowest one they have in common is the LCD.For example:2/3 and 3/4:The multiples of 3 are: 3, 6, 9, 12, 15, 18, 24...The multiples of 4 are: 4, 8, 12, 16, 20, 24...The common multiples are 12 and 24. Since 12 is the least, it is the LCM.

The lowest common multiple is 60.
3600 is one.The lowest common multiple of 3 and 6 is 6
The common multiples of 3 and 12 are the infinite set of numbers that are multiples of 12, which is the least common multiple of 3 and 12. The set is 12, 24, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, and so on.
42
The lowest common multiple is 36
42 is the LCM of 3, 6 and 7. All multiples of 42 are multiples of 3, 6 and 7
3,6,9,12,15,18,21,24,27,30,33,etc are multiples of 3 4,8,12,16,20,24,28,32,36,etc are multiples of 4 These lists have some numbers that are the same. 12, 24, 36 etc. These are all common multiples. 12 is the smallest of these common multiples. Smallest = Lowest (or least) 12 is the lowest common multiple of 3 and 4 Notice that both 3 and 4 divide evenly into all these common multiples. So one way of explaining this is to say that the lowest common multiple is the smallest number that both numbers will evenly divide into. Math books and many teachers will tell you that to find the LCM you must begin by doing a prime factorization of both numbers and then using all factors from each without repeating them. This can be confusing when there one number is a repeated factor in one or the other or both of the numbers you are given to find the LCM.
lowest common multiple is 18
