To find the highest common factor (HCF) of 66, 121, and 143, we first need to find the prime factors of each number. The prime factors of 66 are 2 x 3 x 11, the prime factors of 121 are 11 x 11, and the prime factors of 143 are 11 x 13. The HCF is the product of the common prime factors raised to the lowest power they appear in any of the numbers. In this case, the HCF is 11.
