Glossary for "Is 733 a Prime Number?"

Prime Number: A natural number greater than 1 that has only two distinct positive divisors: 1 and itself. For example, 733 is a prime number because it can only be divided by 1 and 733.


Divisibility Test: A method used to check if one number can be evenly divided by another. For prime numbers, this test shows that a prime number has no divisors other than 1 and itself.


Counting Divisors Method: A technique where we count how many numbers divide evenly into the given number. If the only divisors are 1 and the number itself, it is prime. For example, the divisors of 733 are 1 and 733.


Prime Number Chart: A list of all known prime numbers, which can help identify if a number is prime by checking if it appears in the chart. 733 would be verified as a prime number by its absence of divisors other than 1 and itself.
