Answer

2520

Work Step by Step

1. Write the prime factorization of 315: 5 * 63 = 5 * 7 * 9 = 5 * 7 * 3 * 3 2. Write the prime factorization of 504: 2 * 252 = 2 * 2 * 126 = 2 * 2 * 2 * 63 = 2 * 2 * 2 * 7 * 9 = 2 * 2 * 2 * 7 * 3 * 3 3. The LCM is the combination of all non-overlapping prime factors: 5 * 7 * 3 * 3 * 2 * 2 * 2 = 2520
