No.
No. The 7 times table goes like this 7 14 21 28 35 42 49 56 63 70 77 84 so no 40 is not in the 7 times tables but there is 2 numbers in the 7 times tables that is in the 40s.
Let's look at the 2 and 7 times tables... 2, 4, 6, 8, 10, 12, 14, 16... 7, 14, 21, 28... 14 is the first number to be in both times tables. Therefore, the lowest common multiple (LCM) of 2 and 7 is 14
4*7 1*28 2*14 etc
Because they are tables of the numbers that are the result of "times"-ing a number.
I reccomend going to http://math.about.com/od/multiplication/ig/Times-Tables-Worksheets/ because they are the leaders in almost every thing that has to do with math! It is a great site for help.
