The Greatest Common Factor (GCF) for 12 and 64, notation gcf (12,64), is 4.
* Factors of 12 are 1,2,3,4,6,12;
* Factors of 64 are 1,2,4,8,16,32,64.
So, the 'Greatest Common Factor' or 'Divisor' is 4 because it is the greatest number that divides evenly into all of them.
Draw out and you'll see if make a triangle. Use Pythagorean theorem
you are given c and the other side
So,
c2 = a2 + b2
20^2 = 12^2 + b2
400 = 144 +b2
256 = b2
b = 16
