The least common multiple is 360.
Step-by-step explanation:
The prime factorization of 8 is 2 * 2 * 2 = 2³
The prime factorization of 9 is 3 * 3 = 3²
The prime factorization of 20 is 2 * 2 * 5 = 2² * 5¹
For each prime factor (i. e., 2, 3, and 5), find where it occurs most often and write that value in a new list:
2³ * 3² * 5¹ = 2 * 2 * 2 * 3 * 3 * 5 = 360
