How is the least common denominator different from least common multiple?
a least common (LCD) denominator is a least common multiple (LCM); only it's a fraction and it's LCM is in the denominator's place.
What is the LCD for the fraction 16 and 20 is?
the LCD of fractions is the least common multiple. So we are looking for the least common multiple of 16 and 20 which is 20. So the Least common denominator is 80

That's known as the least common multiple, or LCM.
What are the 2 numbers with a greatest common factor of 3 and a least common multiple of 12 of fraction?
3 and 12
How can knowing the greatest common factor and least common multiple help you when you add subtract and multiply fractions?
Knowing the least common multiple of the denominators will help you find a common denominator when adding and subtracting unlike fractions. Knowing the greatest common factor of the numerator and the denominator will help you reduce the fraction if possible.
