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
The LCM is 45.
45 is the LCM of 15, 9 and 5.
45
lcm(6, 12, 9, 15) = 180 6 = 2 x 3 12 = 2^2 x 3 9 = 3^2 15 = 3 x 5 lcm = 2^2 x 3^2 x 5 = 180
The LCM of 15, 9 and 2 is 90.
The LCM is 585.
The LCM is 90
The Least Common Multiple (LCM) of 12, 9, and 15 is 180.
The LCM of 5, 9, and 15 is 45.
45 (9*5 and 15*3)
The LCM is 45.

The LCM of 3, 5, 9, and 15 is 45.
45 factoring 15=3*5 9=3*3 45=3*3*5 lcm=3*3*5
The LCM is 45.
The LCM of 3 and 5 is 15. The multiples of 3 are , 6, 9, 12, 15, and so on. The multiples of 5 are 5, 10, 15, and so on. The LCM is 15.
