There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
4 and 8, among many others.
9 and 18, among many others.
16 and 32 among many others.
There are many pairs of numbers that have a greatest common factor of 7. Examples: 7, 14 21, 49 35, 63 147, 700 161, 343
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.

to find a factor of a number you have to 1. find the hcf (highest common factor) 2. find how many times the hcf goes into your number AND THAT IS YOUR ANSWER!
12 and 24, among many others.
56 and 112, among many others.
The factors of 17 are 1 and 17. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The common factor is 1. There is only one common factor.
Since 24 is a factor of 96, all the factors of 24 will be common to 96.
