44 = 2 * 2 * 11
66 = 2 * 3 * 11

All the common factors are = 2 and 11.

So HCF = 2 * 11 = 22.
===============================
another method

66 - 44 = 22    check if 22 divides both .  Since it divides both, 22 is the HCF.

Find difference  A - B of given numbers.   if A-B  divides A and B, then A-B is HCF.  Otherwise,  Find difference of  (A-B) and B.  Check if it divides both (A-B) and B.    if so, then difference is the HCF.   Otherwise, continue in the same way, till the difference divides both numbers.
