Question

What is the least common multiple of 36 and 54?

Answer 1

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`□
`2xx`□`xx3xx3xx3`
combined becomes
`2xx2xx3xx3xx3=108`
