First break the numbers down into their prime factors:
9 = 32
15 = 3 x 5
5 = 5
The LCM is the product of all the primes in each list. However if the number occurs in list twice it is only counted once.
So LCM of 9, 15 and 5 = 3 x 3 x 5 = 45
An example: studymaths.co.uk/keytopics/hcfandlcm.html
lcm(5, 9, 15) = 45.
5 = 5
9 = 3^2
15 = 3 x 5
lcm = 3^2 x 5 = 45
45

What is the LCM of 15 9 and 2?
The LCM of 15, 9 and 2 is 90.
What is the LCM of 5 and 9 13?
The LCM is 585.
What is the LCM of 12 9 and 15?
To find the Least Common Multiple (LCM) of 12, 9, and 15, we first need to find the prime factorization of each number. The prime factorization of 12 is 2^2 * 3, the prime factorization of 9 is 3^2, and the prime factorization of 15 is 3 * 5. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 2^2 * 3^2 * 5 = 180. Therefore, the LCM of 12, 9, and 15 is 180.
