What is the sum of the digits of 8165 multiplied by the nearest prime number greater than 8165?

The sum of the digits of 8165 is 8 + 1 + 6 + 5 = 20. The nearest prime number greater than 8165 is 8167. Therefore, the sum of the digits of 8165 multiplied by the nearest prime number greater than 8165 is 20 × 8167 = 163,340.

Math question: What is the largest prime factor of the number 8165?

To find the largest prime factor of 8165, we need to determine if any prime numbers divide it evenly. We start by checking if 2 is a factor, but 8165 is odd, so it is not divisible by 2. Next, we try 3, but the sum of its digits (8 + 1 + 6 + 5 = 20) is not divisible by 3, so 8165 is not divisible by 3 either. Continuing this process, we check if any prime numbers up to the square root of 8165 divide it. It is evident that 5 is a factor (the number ends in 5), so we divide 8165 by 5 to get 1633. Again, we check if any primes divide 1633, but it does not have any prime factors up to its square root (40.4, approximately). Hence, the largest prime factor of 8165 is itself, 8165. In summary, the largest prime factor of the given number is 8165.

Math question: What is the sum of the smallest three positive factors of the number 8165?

To find the answer, we need to determine the factors of 8165. The factors of 8165 are 1, 5, 7, 17, 35, 49, 85, 119, 245, 343, 595, 1225, 1715, 4289, and 8165. The smallest three positive factors are 1, 5, and 7. Adding them together, 1 + 5 + 7 = 13. Therefore, the sum of the smallest three positive factors of 8165 is 13.
