What is the LCM of 40 and 15?

OpenStudy (annie12m):

list out the multipuls of both of those numbers until you find a multipul the same, but it has to be the smallest one

OpenStudy (airjordan200):

well if you do the math 120

OpenStudy (annie12m):

so 15, 30, 45, 60, 75, 90, 105, 120 then make multipuls of 40, 80, 120 so the least common multipul is 120

OpenStudy (airjordan200):

like i said 120
