The LCM of 15 and 18 is 90, which is the multiple of the highest power of prime factors from both numbers (2 x 32 x 5 = 2 x 3 x 3 x 5 = 90).
15 (3 x 5) and 18 (3 x 6)3 x 5 x 6 = 90The LCM is 90.
LCM of 15 9 and 18 is 90. The LCM of 9, 15 and 18 is 90.
The LCM of 15 (which is 3*5) and 18 (which is 2*3^2) is 90 (which is 2*3^2*5).
The LCM is 90.
They are 3 and 90 respectively
Factors: 15 = 3 x 5, 18 = 2 x 3 x 3. The LCM of two numbers = their product divided by their HCF. In this instance the product is 270 and the HCF is 3 so the LCM is 90.
12 and 9. Since both have to be multiples of 3 and sum to 21, the only pairs to consider are 3 and 18 6 and 15 9 and 12 Of these, 3 and 18 have an LCM of 18 and 6 and 15 have an LCM of 30.
LCM of 12 and 15 and 18 is 180.
The Least Common Multiple (LCM) for 15 18 30 is 90.
It is 180
The LCM is 630.
