The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. The greatest factor on one number, such as 5-40 = -36 is itself.
The GCF of 5, 27, and 36 is 1.
The greatest common factor of 54, 5, 36, and 45 is 1.

The greatest common factor of 36 and 40 is 4. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 36 are 2, 2, 3, and 3. The prime factors of 40 are 2, 2, 2, and 5. The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.
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.
There is not a greatest common factor of 40 because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The greatest common factor of 16 and 40 is 8. The greatest common factor of 40 and 55 is 5. The greatest common factor of 36, 40, and 96 is 4.
The factors of 5 are: 1, and 5The factors of 10 are: 1, 5, and 10The factors common to 5 and 10 are: 1, and 5The greatest common factor is 5.
The greatest common factor (GCF) is: 5.
The greatest common factor (GCF) is 5.
The greatest common factor of 900 and 5 is 5.
The greatest common factor of 5 and 10 is 5.
