First, list the prime factorization of each number. If you need help with prime factorization, check out this solver.


12: 2*2*3


18: 2*3*3


Now highlight the unique factors. Remember, highlight the factors that occur most frequently


12: 2*2*3


18: 2*3*3


Now multiply all of the highlighted factors

2*2*3*3=36

So the LCM of 12 and 18 is 36
