What is the greatest common factor of both 9 and 12?

Answer 1

#3#

The greatest common factor is the largest number that two numbers can both be divided by to yield a whole number. #9/3 = 3# and #12/3 = 4#.

By making factor trees you can identify the largest common factors of two numbers. #9 = 3*3# and #12 = 2*2*3#, in this case the only common factor is 3 and therefore the greatest.
