I suggest you learn to use Euclid's algorithm, as the method that is applicable to all sorts of numbers, large and small. Here is the first step:The remainder of the division of 231 by 189 is 42. Therefore, gcf(231, 189) is the same as gcf(189, 42).
Continue by dividing 189 by 42, and getting the remainder, etc.
(For fairly small numbers, an alternative method is to split each number into prime factors, and check the common prime factors between the two numbers.)

∙ 7y agoFactor them.
3 x 3 x 3 x 7 = 189
3 x 7 x 11 = 231
Select the common factor.
The GCF is 3.

∙ 7y ago- You factorise 189 = 3*3*11
- You factorise 231 = 3*7*11
- The common factors are 3 and 11 so you multiply them: 3*11 = 33
- The HCF is 33.
