To find the least common multiple (LCM) of two numbers, you first need to find the prime factorization of each number. The prime factorization of 78 is 2 x 3 x 13, and the prime factorization of 110 is 2 x 5 x 11. Then, you take the highest power of each prime factor that appears in either number. The LCM of 78 and 110 is therefore 2 x 3 x 5 x 11 x 13, which equals 4290.
