You need at least two numbers to find an LCM.
You don't. The LCM refers to integers only.
The LCM of 5 and 4 is 20.
The only common factor between 5 and 9 is 1, so the LCM is simply 5 x 9 = 45.
The LCM applies to integers, not fractions.
The LCM is 120.
It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in each question!
It is typical to only find the lowest common multiple or LCM for a maximum of 3 numbers. The LCM of 3, 2, 7 is 42 and the LCM of 3, 2, 5 is 30.
The LCM is: 125
The least common multiple of 5 and 2 is 10
The LCM is 1455.
Least Common Multiple (LCM) for 3 5 3 5 is 15.
The LCM is 5.
