Since the remainder is eleven, to find the number that divided by a certain number without a reminder, we have to subtract 11.
Therefore, 144 - 11 = 133 and 220 - 11 = 209
Then, we find the HCF of 133 and 209
133 = 7*19 and 209=11*19
HCF of 133 and 209 is therefore 19.
So the answer is 19.
When 144 is divided by 19, the remainder is 11 and when 220 is divided by 19 the remainder is also 11.
