What is the LCM of 15 20 and 40?

Answer 1

Well, honey, the least common multiple (LCM) of 15, 20, and 40 is 120. It's like finding the perfect outfit that all three numbers can agree on - and in this case, 120 is the lucky winner. So, there you have it, math made fabulous!

Answer 2

To find the Least Common Multiple (LCM) of 15, 20, and 40, we first need to find the prime factorization of each number: 15 = 3 x 5, 20 = 2^2 x 5, and 40 = 2^3 x 5. Next, we identify the highest power of each prime factor that appears in any of the factorizations: 2^3, 3, and 5. Finally, we multiply these highest powers together to get the LCM: LCM(15, 20, 40) = 2^3 x 3 x 5 = 120.

Answer 3

The LCM is 120.

Answer 4

LCM of 15 20 and 40 is 120.
