Math Tutor's Solution: 1991 is not a prime number
Methods
Math Tutor Asks: Is 1991 a prime number?
A math tutor would first ask that you define what a prime number is.
A prime number is a number that is divisible by only itself and 1. Since we know that 1991 has more than two factors, then we can come to the conclusion that 1991 is not a prime number and thus we say that 1991 is a composite number.
Math Tutor Suggests: Find out if these other numbers are prime too or not!
When it comes to prime numbers, a math tutor would recommend you learn more about them through practice - so why not have a look and find out if any of these numbers are prime or not?
