Math question: The number 6505 can be represented as the sum of two prime numbers. What is the sum of those prime numbers?

To find the primes that sum up to 6505, we can start searching from the middle: 3252. However, that's not prime. So, let's check for the next closest number, 3247. Unfortunately, it's not prime either. Continuing this process, we find that 3229 is prime. After some calculations, we find that 6505 - 3229 = 3276. However, 3276 is not prime. So, we must continue searching. Eventually, we find that the two prime numbers that sum up to 6505 are 3229 and 3276.

Question: What is the smallest prime number greater than 6505 that is evenly divisible by 3?

The smallest prime number greater than 6505 is 6511. To find this, we start checking numbers after 6505 until we find the first prime number. In this case, we discover that 6511 is a prime number as it is not divisible by any numbers between 2 and its square root, inclusively. Additionally, we observe that 6511 is evenly divisible by 3 as the sum of its digits (6+5+1+1 = 13) is divisible by 3. Therefore, 6511 is the desired number.

Math question: What is the sum of the digits of the number 6505?

To find the sum of the digits, we add the individual digits together. For 6505, the sum is 6 + 5 + 0 + 5 = 16.
