Question

how can you use number patterns to find the least common multiple of 120 and 360

Answer 1

$LCM\ is\ the\ least\ common\ number\ that\ is\ multiply\ of\ both:\\\\ 120:2\\ 60:2\\ 30:2\\ 15:3\\ 5:5\\\\ 360:2\\ 180:2\\ 90:2\\ 45:5\\ 9:3\\ 3:3\\\\ LCM=2^3*3^2*5=8*9*5=360\\\\The\ least\ common\ multiple\ is\ 360.$
