The highest common multiple (HCM) of two numbers is the smallest multiple that is a common multiple of both. For 120 and 130, the HCM is found by calculating the least common multiple (LCM). The prime factorization of 120 is (2^3 \times 3 \times 5) and for 130 it is (2 \times 5 \times 13). The LCM is (2^3 \times 3 \times 5 \times 13 = 1560), so the HCM of 120 and 130 is 1560.
