Yes, the larger the prime number the better.
5 x 7 x 11 x 13 = 5005
A prime number with identical digits is 11.
The factors from greatest to least are: 11,11,5,3,3. The smallest prime factor is 3. You can get a quick idea of this by the fact that the digital root (number that goes evenly into the sum off all digits) is 18 which is divisible by 3.
Larger semiprime numbers are often mistaken for prime if their other factor(s) are not obvious. 40477, for instance, might appear prime at first.
There are no factors of 200, prime or otherwise, that are larger than 200.
