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.
[tex]15=3\times 5[/tex]
[tex]143=11\times 13[/tex]
There is no common factor of 15 and 143. So, we need to multiply all prime factors of both numbers to get the LCM.
[tex]LCM(15,143)=3\times 5\times 11\times 13[/tex]
[tex]LCM(15,143)=2145[/tex]
Therefore, the LCM of given numbers is 2145.
