Factor out the greatest common factor. If the greatest common factor is 1, just retype the polynomial. \( a+7 \)

The polynomial \( a + 7 \) has a greatest common factor of 1 because the two terms \( a \) and \( 7 \) do not share any common factors other than 1. So we can simply write it as is: \( a + 7 \). In situations like this, it's good practice to recognize that sometimes expressions might look more complex than they are! If you encounter polynomials that appear to have a GCF but don't, don't be discouraged—stay calm and carry on factoring with confidence!
