What is the Lowest Common Multiple of 9 and 8?

The lowest common multiple (LCM) of 9 and 8 is 72. To calculate the LCM, you need to find the prime factorization of each number, then multiply each factor the greatest number of times it occurs in either number. For 9 and 8, the prime factorization is 9 = 3 x 3 and 8 = 2 x 2 x 2. Therefore, the LCM of 9 and 8 is 3 x 3 x 2 x 2 x 2 = 72.
