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

It's either GCF (Greatest Common Factor) or LCM (Least Common Multiple).GCF of 3 and 9 is 3, but seven only has 1 as a common factor with the other two, so GCF is 1.LCM of 3 & 9 is 9, and LCM of 9 and 7 is 7 x 9, so LCM is 63.

3 x 3 = 9 3 x 7 = 21 3 x 3 x 7 = 63, the LCM
