Least Common Multiple (LCM)
I. A multiple is the product of a whole number when multiplied by another whole number.
A. For example: 9x1=9,9x2=18,9x3=27,9x4=36, etc... so 9, 18, 27, 36, etc... are multiples of 9.
II. How to find the Least Common Multiples (LCM)
A. Make a list of multiples for the numbers in question
B. Continue the list until their is a common multiple between the two
C. Identify the lowest shared multiple between the shared numbers
III. Tips to finding the LCM
A. Start by making a list for the larger of the two values in question and use your math facts to check in you head if the smaller number is a factor of any of the multiples you are listing
B. Don't forget that the original number is a multiple (multiplied by 1)
C. If you continue your list you will find more factors, but not the "least"
