945
105 = 5*21 525 = 5*105 = 52*21 945 = 5*189 = 5*9*21 LCM = 25*189 = 4725
The Least Common Multiple (LCM) of 7, 27, and 45 is 945. 7 is prime and 27 = 33; they have no common factors so their LCM is 7x27=189. Now bring in 45 = 32x5. The only new factor here is 5, so the LCM of the 3 numbers is 189x5 = 945.
