Given:

The two numbers are 15 and 143.

To find:

The LCM of given two numbers.

Solution:

We have two number 15 and 143. Write factor form of each number.

`15=3* 5`

`143=11* 13`

There is no common factor of 15 and 143. So, we need to multiply all prime factors of both numbers to get the LCM.

`LCM(15,143)=3* 5* 11* 13`

`LCM(15,143)=2145`

Therefore, the LCM of given numbers is 2145.
