15...15,30,45,60,75,90,105,120,135,150
25...25,50,75,100,125,150,175
10...10,20,30,40,50,60,70,80,90,100,110,120,130,140,150,160
The multiples that are the same are Common Multiples. The one that is the smallest is the lowest common multiples. 150 is the LCM. That is your answer

What it the LCM of two numbers whose sum is 40 and whose difference is 10?
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
What is the LCM of 25 15 3?
The LCM is 75.
What is the LCM for 25 and 15?
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.
