#1 Prove this:

2) Write it twice to create a 6-digit #, e.g.135135
3) Divide by 7,
4) Divide by 11,
5) Divide by 13,

#1: 7 x 11 x 13 = 1001, that should tell you something!

1) Well, yes, multiplying a three digit number by 1001 is the same as writing that number twice in a row.
2) Hehe…David told me the answer at a swim meet, but I don’t think I’m allowed to tell the answer either. Hint: What would one want to keep a secret?
And I came up with another riddle!
3) What is the lowest trio of three consecutive odd composite numbers you can find?
(In other words, what three odd numbers in a row are not prime? For example, 3, 5, and 7 fits most of the requirements, except none of them are composite. All three numbers have to be composite.)
