The answer is 270

Yes and it is 11 times 3 = 33
15 x -16 = -240 15 + -16 = -1
The answer is 270
15, 30, 45, 60, 75, 90
5x1 = 5 5x2 = 10 5x3 = 15 5x4 = 20
say if you had to find the LCM of 4 and 3 you can go up in the 4 times table or the 3 times table (4times table will be quicker because it's a bigger number) 4 times table= 4, 8, 12, 16, 20, 24, 28 3 times table= 3, 6, 9, 12, 15, 18, 21 find the number that is in both times tables (has to be the LOWEST common number) in this case is 12 because it is in both lists. Once your able to do this, you'll get use to the idea and you can think of other ways to do it, but this way is good for people that have just started. It would be easier if you know all of your times tables up to 10.

It is not in the seven times table (because the times tables go up to 12), but 196 is a multiple of 7.
tell me
400

16+17+21+15+139=208
If going up to 12 times, then 56 is in the 7 times and 8 times tables.
