What two numbers have an LCM of 90?

To find two numbers with a least common multiple (LCM) of 90, we need to consider the prime factors of 90, which are 2, 3, 3, and 5. To find two numbers with an LCM of 90, we need to pair these prime factors in a way that the least common multiple is 90. One possible pair of numbers could be 18 and 45, as their prime factorization includes all the prime factors of 90.
