This document provides information about working with integers and their properties. It begins by defining odd, even, prime and composite numbers and providing an activity for the reader to identify these properties for different numbers. It then asks questions about numbers belonging to multiple categories and how to identify the different number types. The document goes on to explain prime factorization by finding the prime factors of numbers and provides examples and exercises. Finally, it gives pricing information for online classes and subject downloads through the Yaaka education website.

4. Question1
Are there numbers that belong to more than one group?
Question 2
How do you identify that a number is:
i. Odd
ii. Even
iii. Prime
iv. composite

5. Finding prime factors of any number
In your primary you studied about multiples and factors of numbers.
When to numbers are multiplied together, the product is called a multiple.
The two numbers multiplied together are called factors of a multiple
A multiple has two or more factors

6. Example
The factors of 12 are
1 × 12 = 12
2 × 6 = 12
3 × 4 = 12
Factors of 12 are 1,2,3,4,6,12
The multiples of 4 are
4 × 1 = 4
4 × 2 = 8
4 × 3 = 12
4 × 4 = 16
4 × 5 = 20
4 × 2 = 24
The multiples of 4 are 4,8,12,16,20,24, …

7. Exercise
Find the factors of the following numbers
1. 42
2. 56
3. 36
4. 108

8. Prime factors
Write 36 as a product of its prime factors

36 = 2 × 2 × 3 × 3
This method of determining prime numbers is called prime
factorization.

9. Exercise
