108

Explanation:

Use prime factorization on both numbers (prime numbers that when all multiplied together equal the number)
36:
2xx2xx3xx3

54:
2xx3xx3xx3

Now if you line these factors up, "combine" them, then multiply it out, you'll get the least common multiple.
2xx2xx3xx3xx
2xxxx3xx3xx3
combined becomes
2xx2xx3xx3xx3=108
