63.

The way to answer this type of problem quickly and efficiently is to multiply some of the numbers together. Pair them. In this problem, I paired them into:

7,3

7,9

3,9

For example, I said to myself "7x3=21. Is 21 a multiple of 9? No." Eliminate that pair.

7,3

Next i did 7x9. 63. This is a multiple of all 3 of these numbers. Don't stop there! Check, just to be safe.

7,9

3x9=27. 27 isn't a factor of 7. Eliminate that pair!. You've solved the problem. 63 is the LCM of 7,3, and 9
