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 100 and 435 is 5
5 is a factor of 435. For it to be common, it needs to be compared to another set of factors.
You need at least two numbers to find a GCF.
Short answer: There are none.There is neither a greatest common factor nor common factors of a single number, such as ??, 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.The factors of 65 are 1, 5, 13, and 65.Examples:The greatest common factor of 65 and 195 is 65.The greatest common factor of 65 and 435 is 5.The greatest common factor of 39 and 65 is 13.The greatest common factor of 65 and 73 is 1.
