What is the greatest common factor of 45 and 55?
The greatest common factor of 45 and 55 is 5 To determine GCF you first find the prime factors of each number. For 45 this is (5, 3, 3). For 55 this is (11, 5). Then you take the product of the prime factors that they have in common. In this case the only prime factor they have in common is 5 so the answer is just 5.
