What is the LCM of 66 and 78 and 90?

Answer 1

The LCM is: 12,870

Answer 2

To find the Least Common Multiple (LCM) of 66, 78, and 90, we first need to find the prime factorization of each number.

66 = 2 x 3 x 11 78 = 2 x 3 x 13 90 = 2 x 3^2 x 5

Next, we take the highest power of each prime factor that appears in any of the numbers: 2^1 x 3^2 x 5 x 11 x 13 = 4290.

Therefore, the LCM of 66, 78, and 90 is 4290.
