The first question you need to investigate: Is there ANYnumber that is a common factor of 21, 30, and 44 ?If we can't find at least two of them, then we don't have to worry about "greatest".The factors of 21 are: 1, 3, 7, and 21.The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 44 are: 1, 2, 4, 11, 22, and 44.The only factor common to 21, 30, and 44 is '1'.Technically, I guess the answer to the question is 'Yes'. There is one common factor, so it'salso the greatest.
The common factors of 30 and 21 are 1 and 3.
