JudyThe least number that is divisible by 3, 5, and 9 is the least common multiple (LCM) of these numbers. To find the LCM, we first need to find the prime factorization of each number: 3 = 3, 5 = 5, and 9 = 3^2. The LCM is the product of the highest power of each prime factor that appears in the factorizations, so LCM(3, 5, 9) = 3^2 * 5 = 45. Therefore, the least number divisible by 3, 5, and 9 is 45.
