23 x 52 = 200
There are no two prime numbers that would generate 400. The prime factorization of 400 is 2^4 * 5^2, which means it can be expressed as the product of two powers of primes, but not as the product of two distinct prime numbers.
Mutliplied two prime numbers to get 400?
No.
I'm sure there are more than 2 prime numbers that are 400 digits long.
You will need to multiply six prime numbers to obtain 400: 400 = 5*5*2*2*2*2

No.
The answer is vague but correct . Take any prime number and any other number whose combined digit length is 401 and their product will generate a 400 or a 401 digit number.
There is only one number that equals 400. The number is 400, and it's not a prime number.
The prime factors are: 2, 5

You seek for prime numbers that are approximately 200 digits big, then multiply them. I don't know details about the algorithms, but I understand that for cryptography, instead of using an algorithm that will be guaranteed to give a prime number, an algorithm is used, instead, that has a very, very high probability of giving a prime number. Probably this is done because it is faster.
The sum of all prime between numbers 1 and 400 (2 through 399) is 13,887.
