The “greatest common factor” of 39 and 91 is 13
Solution:
Given that the numbers are 39 and 91
We need to find the greatest common factor. G.C.F is the largest factor that all terms have in common.
To find out the Greatest common factor first of all we need to find the factors of each number individually
[tex]\begin{array}{l}{\text { Factors for } 39=3 \times 13} \\\\ {\text { Factors for } 91=7 \times 13}\end{array}[/tex]
From the above two factors of 39 and 91 we can see the greatest common factor coming out is 13
Hence, the “greatest common factor” of 39 and 91 is 13
