Quizplus · Accepted Answer

The prime factorization of each number is:

85 = 5 * 17
65 = 5 * 13
15 = 3 * 5

To find the least common multiple, we need to take the highest power of each prime factor:

5^1 * 17^1 * 13^1 * 3^1 = 3,315

Therefore, the least common multiple of 85, 65, and 15 is 3,315, which is choice B.
