1.4 Rectangles and Factor Pairs
Two whole #s that are multiplied to get a product is called a
factor pair
______________________.
Example: What are the factor pairs of 36?
1 x 36
2 x 18
3 x 12
4 x 9
36 x 1
18 x 2
12 x 3
9 x 4
6 x 6
 Factor pairs simply represent ways to arrange a given number of
square tiles as a rectangle.
 You can only make two rectangles with a prime number.
A number that can be arranged to form a square with the tiles is
square

called a _______________________.
Draw and label all the ways to arrange 32 carpet squares.
Problem 1.4 Study Guide
The factor pair 3 x 4 is the same as 4 x 3. The product still equals
12, no matter the order in which you write the factors.
Given a prime number, you can only make two rectangles,
since prime numbers only have 2 factors.
Example: 19 x 1
1 x 19
