Question: What is the largest prime factor of the number 8205?

To find the largest prime factor of 8205, we can begin by dividing it by 2, but as it isn't divisible, we try the next prime number. Dividing it by 3, we get 2735, still not divisible. Continuing, we divide by 5, resulting in 547. Dividing further, we find that 547 is a prime number itself. Therefore, the largest prime factor of 8205 is 547.

Math question: What is the sum of the digits of the number 8205?

To find the sum of the digits of 8205, we add the individual digits together. The digit 8 represents 8000, the digit 2 represents 200, the digit 0 represents 0, and the digit 5 represents 5. Adding these values, we get 8000 + 200 + 0 + 5 = 8205.

Math Question: What is the result of multiplying the sum of the digits in 8205 by the product of their differences, then dividing the whole expression by the square root of their sum?

To solve this, we calculate the sum of the digits in 8205, which is 8 + 2 + 0 + 5 = 15. Next, we find the differences between each pair of digits and calculate their product: (8-2) * (8-0) * (8-5) * (2-0) * (2-5) * (0-5) = -48. Finally, we find the square root of the sum of the digits, sqrt(15) ≈ 3.87. Now, applying the given expression, (15 * -48) / 3.87 ≈ -185.98. Thus, the result is approximately -185.98.
