Question #3e533

Answer 1

120

Explanation:

To find LCM:

• First we have to factorize the numbers,

• Then, we take the factors that are not in common.

• Finally we take the common factor that is raised to the highest power:

Factorizing the given numbers:
`8=2^3`
`6=2*3`
`15=5*3`

Then:
`L.C.M=2^3*3*5=120`

(The 3 is a common factor between 15 and 6 and is in both cases raised to the first power that is why it was only taken once).
