The GCF is 3.
The GCF is 3.
If one number is a factor of another number, the greatest common factor will be the lesser number. Example: 3 and 9 3 is a factor of 9 3 is a factor of 3 There can be no higher factor of a number than the number itself. Therefore, the GCF of 3 and 9 is 3.
"Greatest Common" implies two or more numbers. The question only asked about one, the number 3, and is therefore unanswerable. The greatest factor of 3 is 3, but there is no greatest common factor of only one number.
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.
I think you mean the greatest common factor, the greatest common factor is 3.
The greatest number by which both 24 and 9 are divisible is 3. Therefore, greatest common factor is 3.Alternate method:P.F. of 9 = 3x3P.F. of 24 = 2x2x2x33 is the only prime number which is the factor of both 24 and 9.Therefore, GCF = 3.
The greatest common denominator (GCD) refers to a denominator that is COMMON to two or more numbers. You have only one number in the question! The greatest denominator of any number is itself.
Yes. The greatest common factor of 4 and 10 is 2, which is a prime number. The greatest common factor of 51 and 81 is 3, which is a prime number.
-- The greatest factor of 21 is 21 .-- The greatest factor of 12 is 12 .-- 1, 2, and 3 are factors of both 21 and 12 .-- The greatest common ('same for both') factor is 3 .
3 is the greatest factor of 3.
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.
