To find the HCF of 3 numbers you first need to write them as the product of their prime factors. In this case you get:

11 = 11

33 = 3x11

121 = 11x11

The next step is to identify any common prime factors. In this case, all three numbers have an 11 as a prime factor. Therefore, the HCF of 11, 33 and 121 is 11.
