Answer 1

The LCM is 720.

Answer 2

To find the Least Common Multiple (LCM) of 80, 120, and 180, we need to first factorize each number into its prime factors.

80 = 2^4 * 5 120 = 2^3 * 3 * 5 180 = 2^2 * 3^2 * 5

Then, we take the highest power of each prime factor that appears in any of the numbers.

LCM = 2^4 * 3^2 * 5 = 720

Therefore, the LCM of 80, 120, and 180 is 720.

Answer 3

LCM(80, 120, 180) = 720
