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.
For a better illustration of the rule look at 45 and 30.
Prime factors of 45 are (5, 3, 3)
Prime factors of 30 are (5, 3, 2)
The prime factors in common are 5 and 3 and the product of these numbers is 15. Therefore the GCF of 45 and 30 is 15.
The GCF is 5.
The greatest common factor of the numbers 132 and 55 is 11.
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.
