Math question: What is the sum of all the digits in the number 9729?

The number 9729 has four digits. To find the sum of all the digits, we add 9+7+2+9, which equals 27.

Math Question: What is the highest prime number less than 9729 that is divisible by both 3 and 7?

To find the highest prime number less than 9729, we start by checking if 9729 is divisible by 3. The sum of its digits is 9 + 7 + 2 + 9 = 27, so 9729 is divisible by 3 (since 27 is divisible by 3). Next, we check if it is divisible by 7. Removing the last digit, we get 972. Doubling the removed digit (9*2=18) and subtracting it from 972 (972-18=954), we get a number that is divisible by 7. Thus, 9729 is divisible by both 3 and 7. Now, we search for prime numbers less than 9729 that are divisible by both 3 and 7. Starting from the number 9719, which is the highest prime number less than 9729, we subtract 21 (since 3 * 7 = 21) until we find a prime number. By repeating this process, we arrive at the final answer: 9667. Therefore, the highest prime number less than 9729 that is divisible by both 3 and 7 is 9667.

Math Question: What is the largest prime factor of the number 9729?

To find the largest prime factor of 9729, we can start by dividing it by the smallest prime number, 2. After division, we get 4864.5, which is not a whole number. Then we move on to the next prime number, 3. After dividing, we get 3243, which is also not a whole number. Continuing this process, we divide by the prime numbers 5, 7, and 11, but none of them divide evenly into 9729. However, when we divide by the prime number 3 again, we get 1081, which is a whole number. Dividing 1081 by the primes 3, 5, 7, and 11 doesn't give us an even division. Finally, dividing 1081 by the prime number 13, we get 83, a prime number, which means that 9729 = 3 × 3 × 13 × 83. Therefore, the largest prime factor of 9729 is 83.
