Best Answer

To find the least common multiple (LCM) of 9, 21, and 7, we first need to find the prime factorization of each number. The prime factorization of 9 is 3^2, 21 is 3*7, and 7 is a Prime number itself. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 3^2 * 7 = 63. Therefore, the least common multiple of 9, 21, and 7 is 63.
