The LCM is: 180
The LCM of 9 and 15 is 45.
The LCM of 45 and 18 is 90.
It is: 90
45 and any factor of 45 15 and 9 9 and 5
The LCM is 90. The GCF is 9.
It is: 90
It is: 90
The answer is 90.
The least common multiple of 45 and 90 is 90, so you can leave 45 out of the calculations entirely. 40 = 4 x 10; 90 = 9 x 10. Thus, the LCM of 40 and 90 is 4 x 9 x 10 = 360.
45.(45 * 1)(5 * 9)
9 * 5 = 45 (LCM) 45 * 2 = 90 45 * 3 = 135 45 * 4 = 180 etc.
Yes because the LCM of 18 and 45 is 90 and they all have common factors of 9
