The least common multiple of 81 and 108 is 324.
The least common factor of two numbers is the smallest positive integer that both numbers can be evenly divided by. In this case, the factors of 81 are 1, 3, 9, 27, and 81, while the factors of 243 are 1, 3, 9, 27, 81, and 243. The least common factor of 81 and 243 is 81, as it is the smallest factor that both numbers share.
It is: 648
The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 21, 81, and 147 is 3969.
