Study Notes
Greatest Common Factors
- The greatest common factor (GCF) of 24 and 36 is 12.
- The GCF of 42 and 56 is 14.
- The GCF of 36 and 48 is 12.
- If the GCF of two numbers is 4, equations could take the form of ( 4x ) and ( 4y ).
- If the GCF of two numbers is 9, plausible equations include ( 9a ) and ( 9b ).
Possible Equations Based on GCF
- For a GCF of 12, equations might be ( 12m ) and ( 12n ).
- If the GCF is 20, valid equations could be ( 20p ) and ( 20q ).
- For a GCF of 18, consider equations like ( 18c ) and ( 18d ).
- With a GCF of 15, possible representations include ( 15e ) and ( 15f ).
- A GCF of 25 leads to equations such as ( 25g ) and ( 25h ).
- When the GCF is 16, representations might involve ( 16i ) and ( 16j ).
Summary of Greatest Common Factor Characteristics
- The GCF identifies the largest integer that divides two or more numbers without leaving a remainder.
- Equations representing a relationship between two numbers, based on their GCF, typically take the form of multiples of the GCF (e.g., ( GCF \cdot m ) and ( GCF \cdot n )).
