It's simple that 84 and 36 will be divided by only option of 12, so 12 is the HCF.

It is very simple.
First, the difference between 84-36 = 48,
And secondly difference between 48-36 = 12,
Then we got HCF is 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.

36= (2)x(2)x(3)x3,
84= (2)x(2)x(3)x7,
Then take the pair that is common;
2x2x3=12.
84= (2)x(2)x(3)x7,
Then take the pair that is common;
2x2x3=12.
