What is the least common multiple of 9 and 21 and 16?

To find the least common multiple (LCM) of 9, 21, and 16, we first need to find the prime factorization of each number. The prime factorization of 9 is 3^2, 21 is 3 * 7, and 16 is 2^4. To calculate the LCM, we take the highest power of each prime factor that appears in any of the numbers: 2^4 * 3^2 * 7 = 504. Therefore, the least common multiple of 9, 21, and 16 is 504.
