What is the sum of the digits in the number 8231 when it is multiplied by 5, divided by 2, and then subtracted by the square root of 8231? Round your answer to the nearest whole number.

To find the sum of the digits in 8231 when multiplied by 5, we get 41155. Dividing it by 2 gives us 20577.5. The square root of 8231 is approximately 90.7901. Subtracting it from 20577.5 gives approximately 20486.7099. Rounding this to the nearest whole number, we get the final answer of 20487.

Math question: What is the largest prime factor of the number 8231?

To find the largest prime factor of 8231, we can start by checking if any numbers divide it evenly. By testing primes successively, we find that 8231 = 7 * 1175 + 6. Therefore, 8231 is not divisible by 7. Next, testing primes up to the square root of 8231, again none divides it evenly. Therefore, 8231 is prime itself. Hence, the largest prime factor of 8231 is 8231.

Math Question: If 8231 is multiplied by 7 and then divided by the sum of its digits, what is the result?

To find the result, first calculate the sum of the digits: 8 + 2 + 3 + 1 = 14. Now, multiply 8231 by 7: 8231 * 7 = 57,617. Finally, divide the product by the sum of the digits: 57,617 / 14 ≈ 4,115.5. Therefore, the result is approximately 4,115.5 after multiplying 8231 by 7 and dividing it by the sum of its digits.
