break each number down to their prime numbers, so first number is 3, second number is 11 and third number is 3 and 5.
startingstarting with the first number, check it and if the other numbers have a duplicate, cross one of that number off the list for each number you are checking. repeat for each unchecked number (and dont count the crossed off numbers again) until all you have are checked numbers and crossed off numbers. Multiply all the checked numbers for your least common muktiple.
3 * 11 * 5 = 165

The LCM of this is 165.
To find this out, we know that 3=3*1
11=11*1
15=5*3
3, 5, and 11 are all prime factors, so the numbers won't have each other as a factor. So we must multiply, leaving us with 165.
11*3=33
33*5=165

3 = 1 x 3
11 = 1 x 11
13 = 3 x 5
LCM: 1 x 3 x 11 x 5 = 165

Do them 2 at a time.
LCM(3,11) = 33 since 3 and 11 have no prime factor
in common.
LCM(33,15) = 33*15/3 = 165.
The LCM of 2 numbers is their product/their GCD.

Everyone says 165. All three numbers are factors of it. Multiplying all three doesnt help.
