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!
For instance, the greatest common factor (GCF) of 15 and 25 is 5, because 5 is the largest number that goes into 15 and 25 evenly. To find the GCF of small numbers, like 12 or 16, it might be easier to just list all the factors and find the largest common factor, but for big numbers like 490 and 819, you need a faster method. The first step is to complete a prime factorization of each number.
