The Least Common Multiple (LCM) of 5, 10, and 45 is the smallest multiple that all three numbers share. To find the LCM, you first need to find the prime factorization of each number. The prime factorization of 5 is 5, 10 is 2 x 5, and 45 is 3 x 3 x 5. Then, you take the highest power of each prime factor that appears in any of the numbers to calculate the LCM. In this case, the LCM of 5, 10, and 45 is 2 x 3 x 3 x 5, which equals 90.
