Find the LCM of Three Numbers

Create a function that takes an array of three numbers and returns the Least Common Multiple (LCM).

The LCM is the smallest positive number that is a multiple of two or more numbers. In our case, we are dealing with three numbers.

• Multiples of 3 are: 3, 6, 9, 12, and so on.
• Multiples of 4 are: 4, 8,12, and so on.
• Multiples of 12 are: 12, 24, 36, and so on.

Thus, the least common multiple of 3, 4, and 12 is 12.

Examples

lcm_three([5, 7, 13]) ➞ 455

lcm_three([104, 105, 107]) ➞ 1168440

lcm_three([19, 47, 43]) ➞ 38399
