To find the greatest common factor (GCF) of 77, 132, and 143, we need to first factorize each number. The factors of 77 are 1, 7, 11, and 77. The factors of 132 are 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, and 132. The factors of 143 are 1, 11, 13, and 143. The only common factor among all three numbers is 11. Therefore, the greatest common factor of 77, 132, and 143 is 11.
