what is the lowest common multiple for 18 and 27?

18 = 2:3:3:x
27 = x:3:3:3
xx = 2:3:3:3

LCM:
= 2 * 3³
= 2 * 27
= 54

Answer: 54 is the lowest common multiple of 18 and 27.

18+18+18=54 (18x3=54)
27+27=54 (27x2=54)


54=54 so your least common multiple is 54

3*3*3*2 = 54

54

54

M18 : 18___36___54

M 27 : 27___54

LCM = 54

18 = 2 x 3 x 3
27 = .....3 x 3 x 3
------------------------------
....= 2 x 3 x 3 x 3
....= 54
