Lowest common multiple, also known as least common multiple, or LCM, is found by finding the, least common multiple.
For example, if you have the numbers 2, 4, and 8, and you want to find the LCM, you could start by seeing if any of the numbers fit into the other numbers.
2 goes into 4 two times, and into 8 four times. 4 also goes into 8 two times, because of this, the greatest common multiple would be 8.
lets find the LCM of 4 and 9.
You look and see that 4 doesnt go into 9 evenly, so another method you could use is to multiply both numbers together. 4x9= 36. 4 goes into 36 nine times and 9 goes into 36 four times.
I know this doesn't exactly answer your question, but here are some good tips on finding the LCM

What is the common multiple of 120 and 149?
There are many common multiples of 120 and 149. A common multiple is simply a multiple of both numbers. The least common multiple is 120x149, since 149 is prime. (Note: this trick doesn't work on all pairs of number. Although the product is always a multiple, it's not the least common multiple.)
Lowest common multiple of 120?
To find the least common multiple, you need two terms. For example, the least common multiple of 120 and 5 would be 600 and the least common multiple of 120 and 16 would be 240. With one term, there is no least common multiple.
What is the least common multiple of 23 and 39?
Least Common Multiple (LCM) for 39 23 is 897.
What are the least common multiple of 5 and 20?
The Least Common Multiple (LCM) for 5 20 is 20.
What is the least common multiple of 63 and 27?
The least common multiple of 27 and 63 is 189.
