Find the Common Factor in 7x + 14: Step-by-Step Factor Analysis

To find the common factor of the expression $7x + 14$, we need to look at the coefficients and constants.

The expression $7x + 14$ can be rewritten as $7 \cdot x + 7 \cdot 2$.

This shows that each term contains the factor $7$, as both terms contains it: $\orange 7 \cdot x + \orange 7 \cdot 2$ .

Therefore, the common factor is $7$.
