Math question: What is the smallest prime number greater than 7975 that is divisible by both 3 and 5?

To find the smallest prime number greater than 7975 which is divisible by both 3 and 5, we start by observing that any number divisible by 3 and 5 must also be divisible by their least common multiple (LCM) - which is 15. Adding multiples of 15 to 7975, we find that the first few numbers that meet the criteria are 7995, 8010, 8025, and so on. After checking each of these numbers, we find that 8010 is the smallest prime number greater than 7975 that is divisible by both 3 and 5. Therefore, the answer is 8010.
