Explanation
the greatest common factor is the highest number that divides exactly into two or more numbers
to find the GCF List the prime factors that are common to each of the original numbers. Include the highest number of occurrences of each prime factor that is common to each original number. Multiply these together to get the GCF
so
Step 1
List the prime factors or each number
[tex]\begin{gathered} 7=7 \\ 76=2\cdot2\cdot19 \end{gathered}[/tex]
To find the GCF, multiply all the prime factors common to both numbers:
[tex]\begin{gathered} GCF=1\cdot1=1 \\ GF=1 \end{gathered}[/tex]
Therefore, GCF = 1
I hope this helps you
