Part A may be too easy, but hopefully part B and C will be somewhat challenging...

A) What is the 9th and 10th number in this infinite sequence?

1,2,6,12,60,60,420,840,....

Spoiler for Part B (do not look at unless you solved part A or need an indirect hint).

C) As you can tell from both of the last two parts, numbers sometimes repeat. What 5 spots in this sequence are the first 5 that have the same number repeating (hint: it's actually the same 6 numbers in a row)? Better yet, how can you figure this out besides just figuring out the pattern and writing it forever? Better yet, what is that number?
