To find the Least Common Multiple (LCM) of 15, 18, and 30, we first need to find the prime factorization of each number. 15 = 3 x 5, 18 = 2 x 3 x 3, and 30 = 2 x 3 x 5. Then, we take the highest power of each prime factor that appears in any of the numbers, which gives us 2^1 x 3^2 x 5^1 = 90. Therefore, the LCM of 15, 18, and 30 is 90.
Ah, finding the Least Common Multiple is like painting a happy little tree. First, we look at the factors of each number: 15 = 3 x 5, 18 = 2 x 3 x 3, and 30 = 2 x 3 x 5. Then, we take the highest power of each prime factor that appears in any of the numbers: 2^1 x 3^2 x 5^1 = 90. So, the LCM of 15, 18, and 30 is 90.
It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!
