How do you find the greatest common factor of 12 and 18?

Answer 1

6 is the Greatest common factor

Divide both numbers by a common number, such as 2, 3, 5, 7,... or any other number that can be divided similarly to both numbers.

Here

#12 , 18 # Divided both 12 and 18 by 2 hence #6, 9# Further divided both 3 and 9 by 3 hence #2, 3# Hence common factors are 2 and 3 #2*3=6#

The answer is 6, since the greatest common factor among all common numbers is 3.
