Answer:
64
Step-by-step explanation:
You can actually use a diagram. This is when you list similar things and different ones in sections. When you find the prime factorization of 12 and 16...
12
2,2,3
16
2,2,2,2
As you can see, 4 is the greatest common factor. You can drop one 4 and keep the other.
Then, your list should look like this:
12
4,3
16
2,2
Once your list is organized, you can multiply to find you least common multiple.
2*2*4*3=64
