#1
First, list the prime factorization of each number. If you need help with prime factorization, check out this
solver.
5: 5
3: 3
2: 2
Now highlight the unique factors. Remember, highlight the factors that occur most frequently
5:

2:
2
Now multiply all of the highlighted factors
2*3*5=30
So the LCM of 5, 3, and 2 is 30
