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.
The greatest common factor of 55 and 88 is 11.
The greatest common factor of 88 and 72 is 8.
The GCF of 44 and 88 is 44. Since 44 is a factor of 88, it is automatically the GCF.
