2 + 3 + 5 + 431 = 441
3 x 3 x 7 x 7
To find the prime factors of a number, you should start by dividing it by any obvious divisors. In this case, the digit sum of 441 is 9, and so we know that it can divide by 9. Do this and we get 49, which is known from times tables to be 7x7. 9 can be broken down into 3x3. Thus the number 441 can be expressed as 3x3x7x7.
It is: 2*5^4 = 1250
4 is not prime.

No they are not prime numbers because 4 is composite.
4 is not prime.
441 can be written as 4.41 × 102 or expanded as (4 x 102) + (4 x 101) + (1 x 100)

Example: 4 and 9 2 x 2 = 4 3 x 3 = 9 No common prime factors. The GCF is 1. The numbers are relatively prime.
The question is quite ambiguous. If you're talking about all the even prime numbers between 4 and 50, then the sum is zero. No even number, except '2', is a prime number, so there aren't any between 4 and 50..
