To identify the common factors of two numbers, you would start by breaking them down into their prime factors. However, in this case, 23 and 29 are both prime and so cannot be broken down any further. Thus, their only shared common factor is 1. For any pair of non-identical prime numbers, the only common factor will be 1.
