200
There are no factors of 200, prime or otherwise, that are larger than 200.
17 is prime, its only factors are one and itself.
The factors of 100 are included in the factors of 200, but I did not use one to find the other.

The prime factors of 200 are 2 and 5 or as a product of its prime factors 2*2*2*5*5 = 200
200
The three greatest whole numbers less than 200 that each have an odd number of factors are 144, 169 and 196.
The smallest number greater than 200 that has exactly 4 prime factors is 210. This number can be expressed as the product of its prime factors: (2 \times 3 \times 5 \times 7), which indeed yields four distinct prime factors. Other combinations, such as using powers of primes, do not yield a smaller number exceeding 200.
Common factors of 180 and 200 include 1, 2, 4, 5, 10, 20
10 of them.
The factors of 185 are: 1, 5, 37, 185 The factors of 200 are: 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200 The common factors are: 1, 5
