The positive integer 200 has how many factors?

A) 2
B) 10
C) 12
D) 15
E) 24

IMO it should be 12 but the answer is 24.
Can somebody help me understand what am i missing?

200 = 2^3 * 5^2

Using the logic for calculating factore, we can conclude that factore = (3+1) * (2+1) = 4*3 = 12

take 2000 which is a multiple of 200, thus 2000 must have more factors than 200 ( because 2000 have more prime factors) .
if 2000 have (4+1) * (3+1) = 20 factors
so 200 can't have 24 factors
