    Dear Mr. J: Could you explain the reason or reasons for finding the greatest common factor and the least common multiples of two numbers? I have read that the GCF is good for simplifying fractions and the LCM is good for enabling the addition and subtraction of two fractions. Is this the only reason? Thank you.
