3 rows of 8
3 · 8 = 24
The number of rows and the number in each row make the factor pair 3 and 8. The total, 24, is the product.
1 ↔ 242 ↔ 123 ↔ 84 ↔ 6
FACTOR PAIRS OF 24
Example: All Factor Pairs of 24
Each connected pair multiplies to 24. We stop after 4 · 6 because the next pairs repeat in reverse order.
Where would I use this?
Factors Help Us Make Equal Groups
Factors are useful whenever items, people, spaces, or time must be divided evenly.
Buying Packages
A 24-pack can be arranged as 4 rows of 6 drinks.
Making Teams
Divide 32 players into 8 equal teams of 4.
Arranging Seats
Arrange 45 seats in 5 rows of 9.
Planning Time
Split 60 minutes into 4 equal activities of 15 minutes.
Sharing Evenly
Share 24 slices among 6 people so each gets 4.
Future Math
Use common factors to simplify fractions and factor expressions.
