The LCM of 8, 42, and 84 = 168 8 factors into 2^3 42 factors into 2*3*7 84 factors into 2^2 * 3 * 7 The LCM needs to have 2^3 to be divisible by 8 (which includes the 2 and the 22 of the other numbers) as well as a 3 and a 7 in its factors to accommodate the 42 and the 84. Therefore, the LCM is 23 * 3 * 7 = 168

The answer is 42. Just keep doing multiples of each number and keep going until all numbers reach the same factor.

The LCM of 23 and 7 is 161. The LCM of 2, 3 and 7 is 42.
