There are 71 people going to a wedding.  Determine if 71 is a prime or composite, then use this to explain if you can split them into tables so that each table has the same amount of people.

71 is prime because its only factors are 71 and 1.

You cannot split them into equal tables because no other numbers divide evenly into 71.
