Find the Common Factor in 5x + 10: Expression Breakdown

To find the common factor of the expression $5x + 10$, we need to look at the coefficients and constants.

The expression $5x + 10$ can be rewritten as $5 \cdot x + 5 \cdot 2$.

This shows that each term contains the factor $5$, as we can see it shows up in both of the terms: $\orange5 \cdot x + \orange5 \cdot 2$.

Therefore, the common factor is $5$.
