Why is 291 not a prime number
I don't know whether it is or isn't. I'll need to examine it. If it has any other factors besides 1 and 291, then it's not a prime number. The factors of 291 are 1, 3, 97, and 291 . It's not a prime, because it has two more factors in addition to 1 and 291. They are 3 and 97.
