Understand Prime Numbers

In this activity, we will be asking different questions about prime numbers.

Let's recap what prime numbers are.

Prime Numbers

A prime number is a number greater than 1, that can only be divided by itself and 1.

Example:

11 is a prime number - it only has two factors, itself and 1.

11 ÷ 11 = 1

11 ÷ 1 = 11

Composite Numbers

Composite numbers are non-prime numbers.

Composite numbers are whole numbers. 

Composite numbers can be divided by numbers other than itself and 1. 

Composite numbers have more than two factors.

For example, 6 is a composite number because it has the factors: 1, 6, 2, 3.

Let's practise identifying different types of numbers in some questions.
