Math question: If 647 is multiplied by the sum of its digits, what is the result?

To find the sum of the digits of 647, we add 6 + 4 + 7 = 17. Now, multiplying 647 by 17, we get 10,999. Therefore, when 647 is multiplied by the sum of its digits, the result is 10,999. This is calculated by first finding the sum of the digits, 17, and then multiplying it by the original number, 647.

What is the sum of the digits of the number 647?

The sum of the digits is 6 + 4 + 7 = 17.

What is the largest prime factor of the number 647?

To find the largest prime factor of 647, we can start by trying to divide it by the smallest prime number, 2. However, 647 is an odd number and not divisible by 2. Next, we try dividing it by the next prime number, 3, but 647 is not divisible by 3 either. We continue this process, trying to divide by larger and larger prime numbers until we reach the square root of 647, which is approximately 25.45. By using divisibility tests or trying prime numbers up to 25, we find that 647 itself is a prime number as it is not divisible evenly by any other prime number. Therefore, the largest prime factor of 647 is 647 itself. Please note that this answer is assuming we are looking for proper factors (factors other than itself and 1) and that the number 647 is prime itself.
