Answered by Ms. Sue
One way to find the LCM is to find the multiples of the largest number. Then divide them by the other two numbers. Remember that a multiple of 5 must end in either 0 or 5.

12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156

60 is the answer :)
Answered by Ms. Sue
60 is not divisible by 8.

Please do not answer questions when you don't know the answers.

another way is to prime factorize each number and take the highest power of each prime and multiply them together.

For 8= 2^3 or 2x2x2
for 12=2^2x3 or 2x2x2
for 15=3x5

by taking the highest power of each prime and multiplying together we get our solution:
2^3x3x5 or 2x2x2x3x5 which is 120
