Find the smallest positive integer with exactly n different positive factors when n is:
3,4,5,6,10
I am not sure if I should do it like this:
For 3 the answer would be: 1*2*3 = 6 (or is 1 not counted? in that case 2*3*5 =30)
By this approach for 6 the answer would be: 2*3*5*7*11*13?
Or maybe 1,2,3,4,6,12? So the answer would be 12?
I'm not sure how exactly to attack this problem.
