The questioner might have meant to ask, "What are the prime factors of 400?" If this was the question, the answer is 2 and 5.
More often, that locution is used in place of, "What is the prime factorization of 400?" If that was the question, the answer is 2 x 2 x 2 x 2 x 5 x 5.
Mutliplied two prime numbers to get 400?
No.
It is: 2000 by multiplying the highest exponential prime factor from both numbers
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
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
Just go to a table of prime numbers, find the prime numbers, and add them.Just go to a table of prime numbers, find the prime numbers, and add them.Just go to a table of prime numbers, find the prime numbers, and add them.Just go to a table of prime numbers, find the prime numbers, and add them.
The sum of all prime between numbers 1 and 400 (2 through 399) is 13,887.
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.
Everything up to and including 20.
