What is the least common multiple of 78 and 110?
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.
