Let's see what the smallest number that is divisible by each of the denominators.
2, 4, 6, 8, 10, 12, 14, 16, 18, 20 . . .
8, 16, 24 . . .
16, 32 . . .
Which is the smallest number that each denominator goes into?

But 16 doesn't go into 2. And 2 isn't evenly divisible by 8.
When you look for the LCD, you want the smallest number that all denominators will go into.
1/2 = 8/16
1/8 = 2/16
1/16 = 1/16

lcd = lowest common denominator
Maybe you're thinking of lcm -- least common multiple.
