Thanks, hectictar and Asad.....!!!

 

Here's another method.....

 

32 -  12   = 20     20 doesn't divide 12 or 32....so  subtract the two smaller numbers

20 - 12  =   8         8 doesn't divide 12 or 20 .......subtract the two smaller numbers again

12 -  8   =   4         4 divides 12 and 8 , so.....it's the GCF

 

 

 

cool cool cool
