Answer:
use the distributive property
Explanation:
Use the distributive property to rewrite the expression with the GCF factored out.
Example:
ab +ac +ad . . . . has terms with a common factor of 'a'
When the common factor is factored out, the distributive property tells you the equivalent is ...
= a(b +c +d)
If 'a' is the greatest common factor, then b, c, d are mutually prime and no more factors can be removed to outside the parentheses.
