The LCM of 10 and 36 is 180.
10, 20, 30 and so on.
There can only be one least common and that is 70. The next common is 140.
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.
10 = 2 x 5 so LCM is 10
The Least Common Multiple (LCM) for 2 4 is 4.
Multiples of 2 are even numbers. You need at least two numbers to find an LCM.
Both 2 and 5 are prime numbers so their product 2 x 5 = 10 is the Lowest (or Least) Common Multiple. The common multiples of 2 and 5 are therefore any number which is a multiple of 10.
There is an infinite number of common multiples for 2 and 10. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple of 2 and 10 is 20.
No, 2 and 28 are not multiples of 56, they are factors.
