What happens when you dehydrate? By the time you feel thirsty your body is already dehydrated; our thirst mechanism lags behind our actual level of hydration. Research shows that as little as 1 percent dehydration negatively affects your mood, attention, memory and motor coordination.
To find the greatest common factor (GCF) between monomials, take each monomial and write it's prime factorization. Then, identify the factors common to each monomial and multiply those common factors together. Bam! The GCF! To see an example worked out, check out this tutorial!
The greatest common factor between 2 numbers is the largest factor that they have in common. One good way to find this number is to write down all the factors of both numbers and then find the biggest one that appears in both lists. The largest factor they both have is 4. This is the greatest common factor (GCF).
