Answer 1

Given data:

The first number is 3.

The second number is 9.

The greatest commonn factor is,

$\begin{gathered} x=\text{GCF}(3,9) \\ =\text{GCF}(3,\text{ 3}\times3) \\ =3 \end{gathered}$

Thus, the greatest common factor is 3.

Given data:

The given number is 3.

Thus, the number 1 and 3 are the factors of 3.
