The LCM is 420.

The Least Common Multiple (LCM) for 20 25 35 and 45 is 6,300.

The LCM of 12, 15, and 45 is 180. The 15 can be ignored since it is already a factor of 45, next you break down the remaining numbers into their prime factors. 12= 2x2x3 45=3x3x5 You can eliminate 1 of the 3's since it is already a common actor between them So then 2x2x3x3x5=180
