Step-by-step explanation:
91 is the first number that makes it hard to tell whether it's prime or not. Anything smaller, you can check if it's even, or ends in a 5, or the digits sum to 3, or maybe it's the same digit repeated twice, such as 77. Remember that 91 is not prime!
87 factors as 3*29, 89 is prime, 91 factors into 7*13, and 93 as 3*31. All together, that is 3^2*7*3*29*31*89, for a total of 6 different prime factors.
