To find the highest common factor (HCF) of 130, 169, and 195, we first factorize each number: 130 = 2 x 5 x 13, 169 = 13 x 13, and 195 = 3 x 5 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 common prime factor is 13, so the HCF is 13.
