What is the least common multiple of 9 45 and 81?

Answer 1

LCM(9, 4581) = 4581.

Answer 2

To find the least common multiple (LCM) of 9, 45, and 81, we first need to factorize each number. The prime factorization of 9 is 3^2, 45 is 3^2 * 5, and 81 is 3^4. The LCM is the product of the highest power of each prime factor that appears in any of the numbers. Therefore, the LCM of 9, 45, and 81 is 3^4 * 5, which equals 405.

Answer 3

The LCM is 405.

9 and 81 have an LCM of 81.

9 and 45 have an LCM of 45.

45 and 81 have an LCM of 405 (5 x 81, 9 x 45).
