Great Question! Because this is a general question, one might try putting some example numbers to see if you can sense a pattern. Say fraction #1 is 1/3, fraction #2 is 1/4, and fraction#3 is 1/6 -- what would the least common denominator be in such a case? then take fraction #1 to be 1/29, fraction #2 to be 1/10 and fraction#3 to be 1/20 -- what would the least common denominator be in that case? Continue to do so, until you feel that you have found a general answer that can work in all cases. Feel free to watch these other videos that might give you some more insight into least common denominators:

Good Luck!
