The LCM of 15, 20 and 25 is: 300
75 is LCM The numbers are 15 and 25 15 + 25 = 40 25 - 15 = 10 75 / 15 = 5 75 / 25 = 3
The LCM of 5 and 25 is 25. The LCM of 3 and 15 is 15. The LCM of 5-25=-20 and 3-15=-12 is 60
It is: 300

The Least Common Multiple (LCM) for 25 and 15 is the smallest multiple that both numbers share. To find the LCM, you can start by listing the multiples of each number: 25 (25, 50, 75, 100, 125, 150, ...) and 15 (15, 30, 45, 60, 75, 90, ...). The smallest multiple that appears in both lists is 75, so the LCM for 25 and 15 is 75.
If the numbers are x and y then x + y = 40 x - y = 10 so x = 25, y = 15 Then LCM(x, y) = LCM(25, 15) = 75
The least common multiple of the numbers 75, 25 and 15 is 75.
LCM(6, 15, 20, 25) = 300
You need at least two numbers to find an LCM. If that's 15 and 25, the LCM is 75.
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.
