The least common multiple of 45 , 81 = 405
False. The least common multiple (LCM) of a list of numbers is the smallest number that is divisible by each number in the list, not just a multiple. In other words, the LCM is the smallest number that is a common multiple of all the numbers in the list.
70
The lowest common multiple is 384
180
to find the least common multiple of two numbers you must list the factors then you can find out their least common multiple of the two numbers
There is no "most common" multiple of two or more numbers, but there is a greatest common multiple if that's what you mean. But for multiples, the list of common ones goes on and on and on, since every single number in the universe is a multiple.
Since the list of numbers is infinite, there is no such thing as the Greatest Common Multiple.
Their least common multiple is 28
18 is a multiple of 9. To be an LCM, it has to be compared to another list of multiples.
The least common multiple of the numbers 8 and 22 is 88.
Each common multiple of 9 and 10 occurs exactly once (in the list of common multiples), so there is no common multiple that occurs the most. All common multiples of 9 and 10 are the multiples of their least common multiple which is 90.
