Math question: What is the largest prime factor of the number 8247?

To find the largest prime factor of 8247, we start by dividing it by the smallest prime number, 2. We get 4123. Dividing it further by 3 gives 1374. Dividing 1374 by 2 again gives 687. Continuing this process, we finally find that dividing 687 by 7, we get 99. Since 99 is not divisible evenly by any prime number greater than 7, we conclude that the largest prime factor of 8247 is 687.

Math Question: What is the sum of the hundreds, tens, units, and thousands digit in the number 8247?

To find the sum of the digits in 8247, we add 8 (thousands) + 2 (hundreds) + 4 (tens) + 7 (units). Thus, the sum is 8 + 2 + 4 + 7 = 21.

Math Question: If the number 8247 is multiplied by 3 and then divided by the sum of its digits, what is the result?

Let's evaluate the expression. The sum of the digits is 8 + 2 + 4 + 7 = 21. Now, multiplying 8247 by 3 gives us 24741. Dividing 24741 by 21 yields approximately 1178.7143. Hence, the result is approximately 1178.7143. The mathematical steps involved in solving this question include finding the sum of the digits (8 + 2 + 4 + 7 = 21), multiplying the number by 3 (8247 * 3 = 24741), and finally dividing the result by the sum of the digits (24741 ÷ 21 ≈ 1178.7143).
