12 = 2*2*3
28 = 2*2*7
35 = 5*7
In the above factorisations:
The factor 2 appears at most twice
The factor 3 appears at most once
The factor 5 appears at most once
The factor 7 appears at most once
So LCM = 2*2*3*5*7 = 420

∙ 8y agoThe LCM of 12, 28 and 35 is 420.
2 x 2 x 3 = 12
2 x 2 x 7 = 28
5 x 7 = 35
Combine the highest amount of each factor.
2 x 2 x 3 x 5 x 7 = 420, the LCM
