Multiplication (Times) Tables, Products, Factors, Multiples, Prime Numbers and Rules for Divisibility form an important part of the RSA Public Key Cryptosystem. It is important that students know (and that teachers always remind them) when they are busy with these topics, that they are learning fundamental mathematics needed to encrypt data and secret messages. 

This worksheet (with key) focuses on …

Multiplication Tables

Listing Products in a set

Listing all the Factors of an Integer in a set

Listing Multiples of an Integer in a set

The proper notation for Factors, Products and Multiples

The qualities of Prime and Composite Numbers

The Rules of Divisibility of Integers 


Exciting News: This worksheet is the first of 7 worksheets that will teach students ALL the mathematics they need to be able to do RSA Encryption.
