What is the least common multiple of 44 55 and 66?

To find the least common multiple (LCM) of 44, 55, and 66, we first need to find the prime factorization of each number. The prime factorization of 44 is 2^2 * 11, the prime factorization of 55 is 5 * 11, and the prime factorization of 66 is 2 * 3 * 11. To find the LCM, we take the highest power of each prime factor that appears in any of the factorizations, so the LCM of 44, 55, and 66 is 2^2 * 3 * 5 * 11, which equals 660.
