36 = 2 * 2 * 3 * 3.
84 = 2 * 2 * 3 * 7.
The common values are 2 * 2 * 3 = 12.
84 = 2 * 2 * 3 * 7.
The common values are 2 * 2 * 3 = 12.

36= 1*2*3*4*6*9*12*18.
84=1*2*3*4*6*12*14*21.
So, the HCF is 12.
84=1*2*3*4*6*12*14*21.
So, the HCF is 12.

Simple method:
84-36 = 48.
48-36 = 12.
HCF = 12.
84-36 = 48.
48-36 = 12.
HCF = 12.
