Re: Determining n in G=-nFE To find this, you need to balance the half reactions and then balance the half reactions against one another in order to determine the number of moving electrons. When we balance the half reactions we set the number of electrons equal to one another.

To find the greatest common factor (GCF) between numbers, take each number and write its prime factorization. Then, identify the factors common to each number and multiply those common factors together.

The greatest common factor is exactly as it sounds: the greatest factors of two or more numbers. Begin by factoring both numbers. Find all factors that the numbers have in common. You can also determine the GCF if you have both numbers and variables.

To simplify completely, divide both numerator and denominator by the 60. Example: Write the fraction in simplest terms. We find the greatest common factor for the numerator and the denominator: 78 = 2 · 3 · 13 and 84 = 22 · 3 · 7 so the GCF(78, 84) = 2 · 3 = 6.
