Math Question: Find the sum of the digits of the number 6519, then subtract the product of its first and last digits from it.

To find the sum of the digits of 6519, we add 6+5+1+9=21. Next, we calculate the product of the first digit (6) and the last digit (9), which is 6*9=54. Finally, we subtract the product from the sum: 21 - 54 = -33. Thus, the answer is -33.

Question: What is the largest possible prime factor of the number 6519?

In order to find the largest prime factor of 6519, we start by dividing it by the smallest prime number, 2. However, since 2 does not divide 6519 evenly, we move on to the next smallest prime number, 3. Dividing 6519 by 3 gives us 2173, which is clearly not divisible by 3. Continuing this process, we try dividing 6519 by 5, 7, 11, and so on. After some calculations, we come to the conclusion that the largest prime factor of 6519 is 89.

What is the sum of the digits in the number 6519?

To find the sum of the digits, we add up the individual digits in the number 6519. Therefore, 6 + 5 + 1 + 9 = 21. The sum of the digits in 6519 is 21.
