1, 2, 3, and 6 are factors of 6 while 1, 3, 9, and 27 are factors of 27. Notice that the product of the outer elements equal what your factoring as well as the inners.
1x6=6, 2x3=6, 1x27=27, and 3x9=27. Notice the GCF in this case is 3, so factor that out of your initial expression.
Therefore 3(2+9) = 6 +
