Oh, dude, factors are like the friends that multiply together to give you the number you're looking for. So, for 21, you've got 1, 3, 7, and 21 hanging out together. Then, for 30, you've got 1, 2, 3, 5, 6, 10, 15, and 30 chilling. And finally, for 44, you've got 1, 2, 4, 11, 22, and 44 just doing their factor thing.

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.
