Common denominators. These are called "common multiples". For example, multiples of 4 are: 4,8,12,16,20,24 ... . Multiples of 6 are: 6,12,18,24,30,36 ... . The numbers on both lists are the common multiples and they include: 12,24,36, ... . Specifically, the smallest number in any such list of common multiples (12 in this example) is known as the Least (or Lowest) Common Multiple or LCM.
The LCM is 15. The rest are 30, 45, 60, 75 and 90.
It is 12
They are: 24 48 and 72
30
It is: 120
Use some method which you probably already learned, to find the least common multiple. All the other common multiples are multiples of this least common multiple, so you can multiply the least common multiple by 2, by 3, by 4, etc., to get additional common multiples.
The least common multiples of the number 6 and 9 is 3.
3 Least Common Multiples of 12 and 35 are 420, 420 and 420.There is ONLY one Least Common Multiple.The three common multiples of 12 and 35 which are the smallest are the first three multiples of their Least Common Multiple, namely 420, 840 and 1260
Only one can be least. That's 120. The next one is 240.
The Least Common Multiple (LCM) for 3 11 is 33.
Only one can be least; that's 15. Other common multiples include 30 and 45.
The LCM of 3 and 5 is 15. The multiples of 3 are , 6, 9, 12, 15, and so on. The multiples of 5 are 5, 10, 15, and so on. The LCM is 15.
