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.
