The Deep Dive
Prime numbers are the rockstars of the number world—those illegitimate numbers that have exactly two distinct positive divisors: 1 and themselves. From your set, the prime numbers to pull out are \( 7, 11, 13, 19, 23, 29, 31, 43, 47 \). They’re like the exclusive club in a number sense! Now, if you ever find yourself in a situation where you need to identify prime numbers, just remember that you can’t divide them evenly by any other number except for 1 and themselves. So, if you ever doubt a number's primality, try dividing it by smaller prime numbers. If none divide it evenly, congratulations! It's a prime gem!
