Oh, isn't that a happy little question! With 7 elements, you can create many arrays by arranging them in different orders. The number of different arrays you can make out of 7 elements is 5040. Just imagine all the beautiful possibilities waiting to be painted on your canvas of creativity!
Oh, dude, there are like a bazillion different arrays you can make with 18. Okay, maybe not a bazillion, but definitely a lot. You can have arrays like [1, 2, 3, 4, 5, 6], [18], [9, 9], or even [2, 9, 7]. The possibilities are endless... well, not really, but you get the point.
1*422*21 3*146*7
How about: 1*7 = 7 which is a prime number
30

4 (or eight if you count transposed arrays as being different).

3 or 7 - depending on whether you count a transposed array as different. 1*64 2*32 4*16 8*8
identify two composite numbers that each have 8 as a factor
1*422*21 3*146*7
How about: 1*7 = 7 which is a prime number
Number 7 Number 7
30
one
depends on how many people are locked up 7 or 8 numbers
time 8/7
