To find the least common multiple (LCM) of 15, 25, and 45, we first need to find the prime factorization of each number.

15 = 3 x 5 25 = 5 x 5 45 = 3 x 3 x 5

Next, we identify the highest power of each prime factor that appears in any of the factorizations. The LCM is then calculated by multiplying these prime factors together: 3 x 3 x 5 x 5 = 225.

Therefore, the least common multiple of 15, 25, and 45 is 225.
