What are the common factors and greatest common factor of 44?
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.
