First list the factors of 16:1,2,4,8,16. Start with the largest factor (16) and see if it is also a factor of 104 by dividing 104 by 16. When you do you get 6.5, so it is not a factor. So try 8, and when you do you get 13. So 8 is the largest factor of 16 and 104.
52. The largest is 104 itself.
The greatest common factor of 63 and 104 is 1.
The greatest common factor of 104 and 130 is 26.
The greatest common factor of 112 and 104 is 8.
The greatest common factor of 38 and 104 is 2.
Greatest common factor of 39 and 104 is 13.
40 and 104's highest common factor is eight.
The Greatest Common Factor of 26 and 104 is 26.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 104 and 128 is 8
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 104, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.
Since 52 is a factor of 104, it is automatically the GCF.
