In 1 over 8 + 13 over 8 what is the shortest method of finding the GCF?

Question

anonymous · Answer

$$\frac{1}{8}+\frac{13}{8}$$ i assume you want the least common denominator, or least common multiple, not "greatest common factor"

anonymous · Answer

and since both denominators are the same, you can use 8 as your least common denominator and just add up the numerators

$$\frac{1}{8}(1+13)$$ maybe?

anonymous · Answer

Yes, I know it's 6 and mistakenly thought it was called GCF.  But what's a shorter method to use for larger numbers?

amistre64 · Answer

i dont think there is a short method for larger numbers.  large numbers are rather abstract.  computers can perform the tasks that we apply to smaller numbers on large numbers faster.

anonymous · Answer

6?

anonymous · Answer

denominators are the same, add in the numerator

$$\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}$$

anonymous · Answer

Meant to say 2.  Still need a shorter method for the larger numbers though.
