There cannot be a common factor of just one number. To be common there need to be at least two numbers.
The greatest common factor of 12 and 20 is 4
20 - 1,2,4,5,10,20 You can not have a GCF of just one number. But written are the factors of 20.
The lowest common factor of any number is 1
The two number are coprime: their common factor is 1.
lowest common factor of 20 and 33 is 660 mislead you there, dont think there is any greatest common factor because one number is odd and one even
20 and 40, among many others.
4
"Common" means "same for both". There's never anything 'common' about a single item, and in order to have 'common' factors, you need at least two numbers. Now, 9 is never a common factor of 20 and any other number, because 9 is not a factor of 20.
The greatest common factor of 35 and 20 is 5.The prime factors of 35 are 5 and 7The prime factors of 20 are 2, 2, and 5The only factor they have in common is 5.The GCF is 5.The GCF is 5.
The Greatest Common Factor of 20 and 90 is 10, because the factors of 20 are: 20:1,2,4,5,10,20 The factors of 90 are: 90:1,2,3,5,6,9,10,15,18,30,45,90 So, the common factors are 1,2,5,10 10 is the greatest number of them so 10 is the Greatest Common Factor. THE ANSWER IS 10
The GCF is 4.
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.
