No. In order for something to be a factor of a number, it has to be less than or equal to the number.
The greatest common factor is 9 because 18 is divisible by 9 and so is 45. It can not be greaater than half of 18 and 45 is not divisible by 18.
No, 8 is not a factor of 4.
Since 2 is a factor of 8, it is automatically the GCF of the two.
The greatest factor that two or more numbers have in common is known as the greatest common factor, or GCF.

10, it goes into both ten and thirty
I can't explain this fully unless you tell me what 15 is the GCF of.
There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
There is no Greatest Common Factor (GCF) for a single number. The Greatest Common Factor is the largest factor common to two or more numbers.
The Greatest Common Factor (GCF) is: 8
The greatest common factor is 2
The greatest common factor of 42 and 12 is 6.
