Answer 1

Answer:13

Explanation:

First do prime factorizatio. 39=3 times 13

91= 7 times 13

Then you have to find the same number that is 13 there is no more same number so you get 13.

Answer 2

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

`\begin{array}{l}{\text { Factors for } 39=3 * 13} \\\\ {\text { Factors for } 91=7 * 13}\end{array}`

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
