What is the least common multiple for 15 and 20 and 25?

Answer 1

LCM(10, 20, 25) = 100.

There is really no such thing as a "greatest common multiple". Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest multiple.

Answer 2

The LCM is 100.

The GCM is infinite.

Answer 3

The Least Common Multiple (LCM) for 5 20 25 50 is 100.

Answer 4

15 = 31x51

20 = 22x51

25 = 52

LCM(15, 20, 25) = 3x22x52 = 3x4x25 = 300

Answer 5

300
