Factors and Multiples
Objective

By the end of the lesson, you will be
able to find factors and multiples of
whole numbers.

Standard 4NS1.1 – Understand that
many whole numbers break down
in different ways (e.g., 12 = 4 x 3 = 2
x 6 = 2 x 2 x 3).

Looking at the multiplication
table, look at the row that
starts with 4 and the column
that has 4 at the top.
Why is skip counting by 4’s
on this table easy?
When you skip count on this
table, you are saying
multiples of the number.
A multiple is the product of
that number and any whole
number.
What are the first five

Using the graph paper on your desk, try to
draw as many arrays you can that shows 12
squares. (be ready to share).
What arrays did you draw?
1 x 12, 2 x 6, 3 x 4, 12 x 1, 6 x 2, 4 x 3
Do all numbers have factors?
Can you think of some examples of numbers
that only have two factors?
List the first 5 multiples of 7 on your
whiteboards.
Example

Mrs. Sharpe is
arranging desks
in her classroom.
There are 24
desks. How many
ways can she
arrange the desks
so that the
number of desks
in each row is the
same?
Example
How many ways can Mrs. Sharpe arrange the desks
in her class?
 Think of number pairs that result in a product of 24.
 1 x 24 = 24


2 x 12 = 24

3 x 8 = 24

4 x 6 = 24
Let’s watch that concept in

Verughese!!
