**How Can Greatest Common Factors And Least Common Multiples Help You Work With Fractions? The greatest common factor (GCF) can help you reduce fractions. For example, 8/12 reduces to 2/3 because 8/12 = (2*4)/(3*4) = 2/3. Note the ‘4’s in the numerator and denominator canceling. The lowest common multiple (LCM) is used to get the lowest common denominator (LCD) which is needed to add or subtract fractions.**

**What does GCF help us with when working with fractions?** You can use the greatest common factor to simplify fractions. A ratio is an expression that tells us the quotient of two numbers. Since the GCF is a factor of both the numerator and the denominator we can divide both the numerator and the denominator by the GCF to produce a simplified fraction.

**How is the greatest common factor related to fractions?** The highest number that divides exactly into two or more numbers. It is the “greatest” thing for simplifying fractions!

**Why is GCF and LCM important?** While it is important for students to gain procedural fluency in finding greatest common factors (and least common multiples), it is important for us educators to recognize that teaching the various procedures for finding GCF and LCM is not a standalone topic, but rather a foundation skill required for more advanced
