5 5 x 7 = 35 The LCM is 35.

Least Common Multiple (LCM) for 8 42 is 168.

1 can only be an LCM (least common multiple) if the numbers you're trying to find an LCM for are 1 and 1. LCM cannot be smaller than the largest of the numbers you're using.

The LCM is used to convert unlike rational fraction to like fractions so that they can be added or subtracted. Any common multiple will do so the LCM is not that important. However, using the LCM will ensure that the numbers that you have to deal with are as small as they can be.

The LCM is 12.
