Divide both by 3. Divide both results by 171, which is found after dividing 4275 by 25.

26676/12825 = 52/25

You don't state if you're doing this with a calculator or by hand.

You might as well have divided by 9 instead, because the divisibility rule is similar to that of 3. And you were seeing if 8,892
(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 two-digit 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.

And many people call it HCF (Highest Common Factor).
