What is the LCM of 9 10 12?

Answer 1

9.9 18 27 36 45 54 63 72 81 90 99 108 117 126 135 144 153 162 171 180

10.10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180

12.12 24 36 48 60 72 84 96 108 120 132 144 156 168 180

180 is the answer for 10 because the answer must end in a 0 because any number that's divisible by 10 has to end in 0.

Ex. 10 20 30 etc.

180 is the answer for 9 because if you take the 0 off of 180 its 18 and that's the 2nd multiple of 9.

Ex. 180- the 0=18

180 is the answer for 12 because you can multiply to get there, as I did for 12 proof that you can.

Ex. 12x15=180
