### Counting Factors

Is there an efficient way to work out how many factors a large number has?

### Repeaters

Choose any 3 digits and make a 6 digit number by repeating the 3 digits in the same order (e.g. 594594). Explain why whatever digits you choose the number will always be divisible by 7, 11 and 13.

See how many $2$-digit numbers you can find that are divisible by $9$.
What happens if you just use the numbers from $1$ to $8$?
