Divide both by 3. Divide both results by 171, which is found after dividing 4275 by 25. 26676/12825 = 52/25

(the result of dividing 26,676 by 3) just happened to be divisible by 171 (the result of 4,475 divided by 25). You lucked out. If GIjoefan were to be doing it by hand my way, then he/she would have the twodigit number 57, instead of 171, to divide into a dividend.

After dividing the numerator and denominator by their gcd, the result is in lowest terms.

It's short for greatest common divisor.
