10x - 30 10(x - 3) ------------
You need at least two numbers to find a GCF.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.
Divide by two and three until you get to five. (30,1)(15,2)(10,3)(6,5)

It can be. 30 is a factor of 60.
10x - 30 10(x - 3) ------------
Since 30 is a factor of 60, all of its factors are common.
Since 15 is a factor of 30, all of its factors are common.
Since 30 is a factor of 90, all of its factors are common.
You need at least two numbers to find a GCF.There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers.

The greatest common factor (GCF) is 5.
The GCF is 3.
Because 45 is not a factor of 60.
You need at least two numbers to find a GCF.
The square root of 900 is 30 and it is a factor of 900
