It's 60:
4*15=60
5*12=60
6*10=60

Step one: write out the prime factorization of each number.
4 = 2 x 2
5 = 5
6 = 2 x 3
Step two: Line up ALL matching factors. To represent a blank space, I'm going to use a 1 (since 1 times anything is itself).
2 x 2
1 x 1 x 5
2 x 1 x 1 x 3
Notice how I lined up the common 2, for the prime factors of 4 and 6.
Now, create a new product by looking at each column. That is
2 x 2
1 x 1 x 1 x 5
2 x 1 x 3
Will be
2 x 2 x 3 x 5
This will be the LCM. We calculate this to get 60.

4= 2x2
5
6=2x3
Pair up the commons in all three- there are no ones.
Just multiply.
The answer is 120.
Reduce it and the answer is 60.
The LCM is 60.
