88 8 x 11 (2x4) x 11 (2 x (2x2)) x 11 Since 2 and 11 are prime numbers, the factor tree is complete.
A factor tree will show you the prime factorization of 88. Comparing that prime factorization of 88 and another number will you show you the GCF between the two. You need at least two numbers to find a GCF.

To find the answer you have to find a common factor of 55 and 88. The most obvious one is 11. 55/11=5 and 88/11=8. Because there is not a common factor between 5 and 8, 55 is now 5 and 88 is now 8. So your simplest form is 5 over 8.
