Quizplus · Accepted Answer

To find the LCM, we need to factor both numbers:
9 = 3 x 3
15 = 3 x 5
The LCM is the product of the highest power of each prime factor:
3 x 3 x 5 = 45
Therefore, the answer is choice C. 9 can be factored into 3*3
15 can be factored into 3*5
The LCM of 9 and 15 is the product of the highest power of each prime factor, which is 3*3*5 = 45. Therefore, the correct answer is C (45).
