8 (1,2,4,8)
24
88 has exactly eight factors (1, 2, 4, 8, 11, 22, 44 & 88)
Indeed, the number 16 has 5 factors, 1, 2, 4, 8, and 16.
Well, If we looked at this way: (224) = 16777216, so this number has exactly 24 factors. (324) = 282429536481, so this number has exactly 24 factors. (510)(210)(34) = 810000000000, so this number has exactly 24 factors.
8
Oh, dude, the least number with exactly 8 factors is 24. It's like, got factors 1, 2, 3, 4, 6, 8, 12, and 24. So, yeah, that's the magic number with just the right amount of factors to make it cool.
