The least common multiple (LCM) of 2, 5, and 9 is the smallest multiple that all three numbers share. To find the LCM, you can first find the prime factorization of each number: 2 = 2, 5 = 5, and 9 = 3 x 3. Then, identify the highest power of each prime factor that appears in any of the numbers: 2 x 3 x 3 x 5 = 90. Therefore, the LCM of 2, 5, and 9 is 90.
