Example: 30 and 42 List the multiples. 30, 60, 90, 120, 150, 180, 210 42, 84, 126, 168, 210 Once you hit the same number, you've found the LCM.
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.
Let's see . . .(100 numbers) x (30 multiples for each number) = an answer with 3,000 parts to it
That's an infinite list, started by 15, 30, 45, 60 and so on.
Least common multiples do not use zero as a multiple, as the LCM for any number and zero is zero.
no because not all numbers go into the number 30
No because it will take for ever to finish.
The multiples of 3 up to 30 are: 3,6,9,12,15,18,21,24,27,30.The multiples of 5 up to 30 are: 5,10,15,20,25,30.The only common multiples are 15 and 30.The LCM is: 30
Example: 30 and 42 List the multiples. 30, 60, 90, 120, 150, 180, 210 42, 84, 126, 168, 210 Once you hit the same number, you've found the LCM.
There are an infinite number of multiples of any number. Therefore, it is impossible to list all the multiples of 3 and 4. A list of the first 10 multiples: Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40
The common multiples of 12 and 30 are numbers that are divisible by both 12 and 30. To find the common multiples, you can list out the multiples of each number and find the numbers that appear in both lists. The common multiples of 12 and 30 are 60, 120, 180, and so on, as these numbers can be evenly divided by both 12 and 30.
That's an infinite list.
Any list of multiples is infinite; much too long to type out here.
Example: 5 and 7 List the multiples of 5. 5, 10, 15, 20, 25, 30, 35, 40... List the multiples of 7. 7, 14, 21, 28, 35, 42... The LCM is the first number that appears on both lists.
LCM = 30
41
The multiples of each number from 1-30.
