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.
